Input: I (M20) was talking with my girlfriend (F18) and the subject of an ex of her’s came up and I made  a rude comment about him and she didn’t take it very well.

For some background we’ve known each other since before middle school, grown up together and officially started dating about 10 months ago. She’s amazing and I love her and being with her. In our social group there isn’t much dating or many actual relationships so the subject of past relationships is a little more sensitive for us. She was in love with this guy a long time ago,  when she was around 14 IIRC, he lived in another country so she’d visit and see him but I never met him or knew much about him. On my side of things I’ve been in a couple past relationships and in particular there was this one girl that I was crushing on pretty hard for a while before I was interested in my current girlfriend, my current GF was my go to to talk about stuff like this so she heard a lot about her, to an extent it’s a little embarrassing now. I never got in a relationship with this girl, she has a reputation for being on the provocative side of things and would always play with guys, definitely not a good girl to be interested in. 

In any case it’s occasional for my current GF to bring up this girl (who she hasn’t met before) and talk really bad about her, calling her a slut, saying she hates her, etc. 
She really doesn’t like her and I understand it to an extent because she’s protective of me and in a way I love that she is so it doesn’t really bother me.

Today however we were talking about types of guys she’s attracted to and as she was describing her type this guy who we’ll call Mark comes up in conversation, Mark isn’t exactly the most attractive guy, very odd looking and not what you’d generally call attractive. I have nothing wrong with him personally whatsoever, their relationship was a long time ago. 

So jokingly I tell her that there’s no way she likes this guy for her looks, she says he’s cute and this is where I might’ve messed up, I asked if he was all there, which I definitely could’ve worded better. I didn’t want to say anything bad if there was something, so she tells me he’s all there, he used to be blind but he can see now. I then messed up and made a dumb joke and said something along the lines of  “Did he go blind looking in the mirror?” And some other quip I don’t remember about his forehead... oops that was probably uncalled for. We make jokes pretty frequently about other people but not mean-spirited, except for when she talks about my Ex. Anyways girlfriend goes dead silent and didn’t say anything for a bit, then we get into a big discussion about what’s okay and what’s not. I told her I was joking and didn’t mean anything bad towards him. The conversation ended with her really upset with me and me getting the impression she might have feelings for this guy who she still occasionally sees when she visits his area. 

Great.
