So there was this guy at work and i hung out with him ONCE AND HAD SEX (i know i already sound like an easy hoe buttt i swear im not he was only the second guy i had been with ) any way i found out he had a GF And apologized because that was extremely not in my character. We still continued to talk and laugh ONLY at work because he was a coo person. Then another guy came along we started talking and sooner or later we got together and i love him more then he'll EVER KNOW. he asked me to stop talking to the guy that I messed with prior to him at work but we still continue to laugh and talk and my boyfriend would come into our class that we worked in and catch me talking to him we got into plenty of arguments about it and now I don't talk to the guy at all anymore because I understand how bad it hurt my boyfriend he always brings it up and tells me that I obviously cared more about the other guy than him since I didn't stop talking to him which is not true he'll constantly and randomly bring it up it makes me cry because he's hurt sometimes he said some really mean things because I know he is hurt or he'll accuse me of talking to men at my new job and being disrespectful to him he thinks that while he's away I'll have men in and out of our apartment or I'll run into an ex while he's away. At this point i i tell him EVERY CONVERSATION i have with a man even if a man compliments me or looks my way. I don't know how to help him get over it and show him that I am sincerely and honestly sorry
