For context, I've been in a previous relationship that ended with me finding out id been cheated on several times within the space of 3 years.
A few nights ago, my partner and I went into our nearest city for some drinks to celebrate a friend's promotion. We were all at a bar chatting - some had had more to drink than others. My OH whispered to a friend and visibly looked a very pretty girl (not one we knew) up and down in a very obvious way. I mentioned it in passing later on and the response I got was "I expect you do it all the time and I wouldn't make a deal out of it. I can't only be attracted to you, look at you".
AIBU to be upset about this? He's emphatically said he would never cheat on me and sober says he doesn't look at other people like that (??). He seems to have forgotten the whole conversation but it's burst my happy bubble. Am I being ridiculous?
