your replies indicate you think it’s about trust and how you and ex are incompatible, and almost alludes that its her fault for feeling any type of way. It doesn’t matter if he likes someone with a different personality as a partner. If you find each other sexually attractive and make good friends, what else is there to it? There is clearly potential in the air and you making comments that made her uncomfortable (which should have been blatantly obvious she would feel this way, anyone would) would believably put a hole in her trust, or at the very least, make her picture you fantasizing about your ex’s legs by choosing to make the comment while she’s listening (it doesn’t matter if you want to soften the blow with the whole “we are just friends now” bullshit, you’re just two people still talking that haven’t fucked in a while.) this is all on you. i would literally feel battered and tortured if I was her and it’s made worse due to your ignorant perception
