This describes almost every friendship I've had. There are very few people who continue to show interest in talking to me after a while. I only have one person who isn't family that I still talk to, I don't exactly know why he continued to talk to me after all this time, but he is very similar to me; he isn't autistic, he actually believes he is a high-functioning sociopath, which I don't disagree with as many of the traits are there, just not severely enough to cause him major problems.
Other than him though, no friends to speak of. If I try to initiate a friendship with someone it dies out very quickly. If I try to keep a friendship going I am not ever successful. Some friends would even start to ignore me, and I still don't know what I did to this day. If I put myself out there socially I'm sure I'd get a lot more of this than I already have, so I usually just try to be satisfied with my own company. I talk to my younger brothers and my mom regularly, occasionally my older siblings. That's pretty much it. I'm resigned to having a pretty solitary life, and at least at this point in time it doesn't bother me too much.
