The guy I was with was insecure and extremely jealous but I still stayed with him for more than a year. Whenever we fought, he would pretend to realize the error of his ways and accept responsibility for things that were his fault, and I would end up forgiving him thinking he's changed. Then if/when it gets brought up again by either of us he would play the victim and blame me for whatever happened. He gave me shit for hanging out with one of my guy friends and eventually forbade me from seeing him. With other guy friends he would act perfectly fine with me hanging out with them, but when we fought he always implied I was cheating on him with these friends, although he said before how much he "trusted" them. He told me I shouldn't see a therapist for depression because how would that make him look, dating a girl seeing a therapist? He was always so insecure with his appearance. He wasn't buff or anything but I loved everything about his body, told him that constantly, but his response would usually be disbelief along with the phrase, "I bet you would prefer me with a six pack though. What girl wouldn't?" When I dressed up really nice for a date night one night he said "Wow, every guy is looking at you tonight" and when I got upset he followed up with "No it's okay, I mean girls dress up to get attention anyway right?" During arguments he would go crazy, literally saying anything he knew would upset me, including my favorite "You lying fucking whore." I've never in my life cheated on him, and whenever there was a reason for him to suspect it I made sure to do what I could to get rid of that reason (including ending a friendship), but he always still thought I was cheating on him. We had an on again/off again relationship before but the end came when I found out he had cheated on me multiple times. We broke up for good more than two months ago. Looking back, it was the best decision I've made.
