I had an autistic boyfriend. I didn't know until the middle of our relationship, but before I figured it out he confessed to me that when he was younger he did have a "little autism", implying he didn't anymore. I thought that was weird as I don't think autism just... goes away? He was not terribly an affectionate person and has an aversion to sex. Which sucked for me since I am quite a sexual person. He didn't quite understand my feelings even when I expressed them. He often said insensitive things to me that made me upset, but never understood why even when I tried to explain. He had trouble with making friends such as I (though I am not autistic). Now for more of my experience with him... he was extremely negative and a massive whiner. Every day the littlest inconvenience ruined his entire day and mood. Can't get passed an obstacle in a game? He rages and is sour the rest of the day. Accidentally burned his finger on a stove? Life sucks!! He lived with his parents and played video games and browsed the internet the entire day. He had no job and he claimed he couldn't work because he thought he couldn't handle anything negative because he was sensitive. Which I thought was bullshit. He was very capable of working he just didn't want to do it. He wanted to leave his situation, but didn't want to help himself at all. Every time I mentioned to him ways he could help himself, he shot them down immediately with a petty excuse. Another thing he had going was he was massively co-dependent. Eventually I felt more like his mother than his girlfriend or some type of outlet he can throw all his negativity on. I had to leave him. I certainly don't think all autistic people were like him, but that was my only encounter with an autistic person in my life.
