I (18f) boyfriend (19m) have been living together for the past 6 months and have been together for the past year and 2 months. This all started when we first got together and he made a joke about this one girl that I barely knew but went to highschool with she was known as the school hoe. She was also known to have Chlamydia (he didn’t find out until after he had sex with her ) but he decided to lie to my face and told me he never had sex with her. Then he would start telling me things like he has always used condoms,he didn’t talk to other girls a lot,he was never a hoe. This whole time I mind you we both got that sti in the beginning of our relationship and had lots of arguments over it he had gaslit me for months making me think I gave it to him and I was such a nasty person because I had sex with a couple people here and there before him. This had all started the other night on Friday last week he decided after a year to tell me that he gave the sti to me and as well have never worn condoms anytime he was having sex with other girls and turns out he did have sex with that one girl he said he didn’t!!! Whenever he was telling me about it he told me in a type of tone that he didn’t care and laughed it off and right now Ive been trying to be nice but everytime im around him I just think what else is he lying about and I’ve been so mean to him lately because of what he did made me so disappointed (Am I the a**hole?)
