What you said and your reasoning for saying it was NOT a social faux pas! What you said was totally normal and fine, and is something couples do all the time! My S/O and I (who is also autistic) love talking about hot people! We've made entire lists of movies to watch together just because they star our favorite celebrities! :P Sure it's led to us watching some crappy movies, but never to a fight because we trust each other, and know that there's not a chance in hell we'd leave one another for a celebrity (or someone who looks like one) <3 It sounds like your boyfriend was the one acting out of line here, although I understand that having low self-esteem can be rough to deal with. Jealousy is a natural reaction, but what isn't right is the way he's making you feel bad about it :( You did nothing wrong, and you sound like very sweet and loving partner <3

Has he looked into therapy, or anger management classes?
