long distance relationship, messy breakup (and cheating)

Reagan
i had a boyfriend earlier this year where things started been going downhill between us ever since i left for college. we had only been dating for two or three months before i left and then continued dating for eight months while i was away for school. the last three months of our relationship were way to stressful for me but every time i told him i wanted a break he would refuse and say they we could work on it and it just got worse and worse. finally, for the entire week before we officially broke up, i told him that i wanted us to take a break every day and we kept fighting about it. the night before we officially broke up (aka the night before he accepted that we were beaking up), i was drinking with friends and told him to come down and visit because i wanted to talk to him about what was going to to his face (he had told me multiple times that if i broke up with him over the phone, he would show up at my dorm and i didn't want that). that night, i kissed a friend of mine that had been helping me the whole night. (bonus round: the friend was a girl and although i told my boyfriend that i was bi pretty much on our first date, he said to me that that was only bi after i kissed her) the first thing i did the next morning was tell my boyfriend and it was the hardest and most embarrassing thing i've ever had to do. i've been told that it's a grey area between cheating or not since he knew that we were just about broken up at the time but i still feel terrible about it and he still likes
to use it without context, making it sound like i was hooking up with loads of people and keeping it secret.
