My mind worries that some of them who used to tell me they hoped I would meet someone who could be my girlfriend no longer feel that way.
I want you to be in a relationship, but your chances will increase if you get practice socializing in positive ways with others. That will maximize your chances whenever you have opportunities for dating. Then you'd perhaps feel more comfortable there and the other could see your social skills and other good qualities you have there too. This means being positive in your communications and having opinions about topics when others bring that up, and asking questions related to that topic too, when lulls occur or when you need any clarity for any points they make and to make the conversation flow better.
Practice socializing with any local friend and some online others through messaging, chat or phone, starting with your interests if need, but then alternating to discuss theirs interests, too, to show give and take and any empathy for their social needs and interests too. Also, engage others with replies as much as possible when they engage you through any type of communication, regardless if they are a man or women or your personality type or not, and regardless if you like them or not. See those social attempts as you getting practice more so than you wanting to be their friend, as that is not realistic to expect the latter until after many successful communications.
Replying to others and socializing with persons of different types, and not just for dating, shows politeness, well roundedness, less pickiness and less neediness. Even if you are needy, you do not want to advertise that. Even if you are feeling negative or very shy, try not to talk much that much, too, when talking to new persons who prefer a more positive start to talks. Attempts at socialization, no matter how initially awkward, shows not only friendliness but you are trying to develop yourself and be the best version of yourself through meeting others. Persons are often more attracted to others, or more engaging there when that other shows less anxiety, fear and impatience.
The more practice you get, the more social you will become, if you take more positives than negatives out of that communication, thus the more likeable you'll be to more persons you engage with. Initiate conversations with persons too, by asking a relevant question or by giving comment especially to those you think could be more receptive to that or who'd reply back. Yes, many with Autism can find it harder to pick up on nonverbal cues, but in general, if the other has either a smile, better eye contact and/or seems less busy, the better the chances they'll be open to at least saying Hello back to you, if not want to engage you for more, the more you seem nice in a non-pushy, more easygoing way.
Try to understand that it often takes two to make a conversation flow. Even if you are shy, the other can lose interest if they are doing most of the effort or talking and if you show much anxiety or negativity. So, besides both having to be receptive enough for a chat, and with enough self esteem, positivity and social skills there, look for pauses where they expect you to reply back, and when a topic seems exhausted or you have nothing more to say there after any questions there you asked too, don't be afraid to switch to another topic of discussion. Socializing is supposed to be seen as relaxing or fun, or to inquire or learn more, and not just conversing about one topic you like for longer talks or in getting a relationship, but as a shyer person if you are not there yet, you can do other things too to increase your mindset and social skills.
Let's say you just talked to a local friend and need more social practice than with them? There are many other things you can do too. Research a list of a hundred or more random topic prompt questions, write them down or print them out, and pick a few or several out each day and give answers out loud to those in front of a mirror. Also, turn the tv or radio on listen to a question or comment made from a voice there, turn the volume down then, and reply at length as comprehensively and relevantly as possible. Keep doing that to various programs, channels you go to for several weeks, and to the various questions and comments you hear there, and focusing too on having less pauses for sentences voiced, and less anxiety and more smoothness shown in your speech.
Also, at home imagine yourself having back and forth positive communications with others, both short, medium and long talks, visualizing yourself succeeding there with your calmness, more open and relaxed posture, any smiling and better eye contact, and your flowing speech, etc. Imagine one by one greeting many different types of others, and in various settings, with the other you meeting in the visualization appearing receptive to your attempts and returning the communications in a friendly and positive way, with equal abilities and taking turns there. By having several of these more positive social daydreams daily, over time these can over time trick your mind to think they actually occurred, giving you positive reinforcements there.
The key I feel for most positive social experiences is to appear relaxed, somewhat confident and friendly, and without coming across as too needy, shy, negative and/or dysfunctional, but to not assume others are always in the frame of mind to talk too. But, when those approach you and engage you, if you do not attempt to return that nice gesture, or in a reasonable socially accepted way, then in general that can be a turn off to most, as it implies either someone too avoidant, snobbish, socially inept or looking for only specific persons, or it can come across that other want to jump over step to get friends, relationships, etc. By being polite and having some social skills to those who were polite too, and that other trying to give you a self-esteem boost or social practice attempt, etc, this shows partly ones social etitiquette, empathy and efforts.
Markness, also pay attention to any postures, expressions and eye contact in yourself, not just in others to determine their possible receptiveness, when any face-to-face contacts are made or to be considered. Most NT's for instance may be more apt to approach and attempt socializing with one with better eye contact and more friendly smile and open postures. Those with eyes averted too much, crossed arms, head and shoulders down or away, and neutral or anxious facial look may be seem less approachable than one with the opposite than that. And by being in a more social looking physical state this can often instantly get at least temporarily many into a more social, confident and relaxed mood. You can practice these at home by looking in a mirror, etc.
But, having said all of the above, if you want to be totally yourself, you still could be in a relationship one day, but your chances will be greatly limited. You'd then more likely attract some desperate woman with many problematic issues herself, or the very empathetic and mentally strong woman who feels sorry for you and had much compassion and strength to want to do everything for you to make you happier, and/or with her hoping for more functionality in you during her strong many efforts in the relationship. In that case, you'd have to target often your search where those women would be more receptive to those untraditional guys who had shyness and many executive function issues. So, being proactive there in finding those places where you'd be able to be more yourself, and where they'd allow for limitations and difficulties, at least for short term, that is an option too.
