I am in my late 20s and don't really have any IRL friends. The only person I see on a consistent basis is my partner. Neither of us really have a social life and we don't leave the house often except for going to work or when we travel for dog shows.
Most people don't like either of us very much. I am standoffish and I can be very blunt. I try to be nice but everyone thinks I'm weird either way. My partner is extremely awkward and not really age-appropriate. He is in his mid 20s and still plays Nintendo DS games and has stuffed animals. Neither of our main interests are really socially acceptable either. We breed and show dogs and everything I do has to do with dogs in some way or another. It really puts people off. Like they are interested when I first tell them about it, but when they visit our house they think I'm the crazy dog lady and they generally don't come back a second time. The difference between myself and my partner is that I'm capable of having a normal conversation about something other than dogs. I actually have a wide- and fairly normal- spectrum of interests. My partner is not particularly capable of talking about anything other than his [somewhat childish interests/obsessions] in a social situation, and at our age people really don't want to talk about those things.
My partner is very aware (and sad) that he doesn't have friends because he knows it has to do with how people react to his autism.
I also think people are uncomfortable around me because I have a service dog but that's kind of self-explanatory. People with obvious disabilities, whether we like it or not, make normal people uncomfortable.
I want both of us to be able to make friends but I don't know how to get past the barrier of people perceiving us as weird or awkward. I haven't really socialized since I was in college and that was a long time ago.
