First of all, I would like to point out one problem right away. This line:
"They at times seem to like me, but then I feel like a drag to them after a while"
Right. That. That's an issue. Unless someone specifically TELLS you they feel that way... it is not wise to assume. In that case, it's YOU feeling that way, being down on yourself. You have no way of knowing what THEY are thinking unless they say so, but you are assuming so nonetheless.
And remember the nature of the type of condition that most of us on this forum have. One of the biggest "symptoms" is not being able to read/interpret social cues, whether offline or online, doesnt matter where. For example: say you're talking to someone online directly, right? And suddenly, they go silent. They stay silent for awhile. Chances are, at this point, you're thinking something like "oh they're tired of me now". In reality, it could be a bazillion possible things. Hell, in my online chats with people, I often go silent. One major reason is simple: I have a dog. He needs constant attention and I must check on him frequently. So I may step away from the computer at random to give him attention. It has nothing whatsoever to do with the person I'm talking to... it's just that yeah, I'm at the computer, but I still have other things going on as well. I dont JUST talk. But that doesnt mean I've gotten tired of the other person, or lost interest in the conversation. And not even just that... sometimes there are screwball technical issues. But you cant know what kind of insanity Windows is producing on their end unless they tell you what is going wrong. So what you get is.... silence, or perhaps someone suddenly appearing to go offline. It doesnt mean anything whatsoever in relation to you, but could mean about a million things that have nothing to do with you at all.
The reason why I'm saying all this is because I've been doing this for... too long. I dont really want to know how long, really. MOST people I meet, I meet them online somehow. Some have become long-lasting friends, people I met years ago and still know today. Some I have later even met in person a couple of times. But suffice it to say, I know that online friendships CAN work. You just have to understand the nuances of this type of thing, and remember that when a person is sitting at a computer talking to you, the computer is not the only thing currently existing near them.
And, on top of that... dont forget that some days, the other person just might not be in a very social mood. I know I get like that sometimes. If I'm having one of my bad days I keep to myself and wont even make my presence known. I doubt I'm the only one that does that sort of thing.
If you want to meet new friends though, you're in the right place. Heck, chat with me, if you'd like. It sounds like we have some of the same interests. Gaming being my main one, reading being another. I'm always up for a chat, though as I said I do have.... "interruptions" at times.
