I think that for most people, friendship largely consists of social ritual. Aspies aren't wired for this, and as it is mostly about nonverbal manipulation of someone's emotional state and ego, aspies usually can't bring themselves to care about it much. Besides, the NT social dance is too nuanced, subtle, subconscious and real-time to be faked, IMO. I have a couple of real, close friends, and then other "acquaintances" or "friends" with whom I share an interest or have some other reason to interact with occasionally. I cannot and do not do the normal friend thing: "Met some cool people. We went out for drinks, then to this party, yadda yadda yadda..."
Don't get down on yourself. You are probably just someone who needs certain rare sorts of people to be friends with. Most neurotypicals have the potential of getting on well with a great many people. We have to be more patient, and engage in OUR sort of friendships, as most of us cannot carry on conventional friendships. That is not to say that out relationships cannot be full of trust, mutual support, carefree acceptance, humor, etc, but our paths to said benefits might be rarer and different than the norm. I have found a couple such individuals here, and a couple more IRL through my special interest. Be yourself above all. This is a very nice, safe place to do just that.
