My [24/F] boyfriend [25/M] of 5 years, broke up with me this week stating he doesn't feel the same about me anymore. Turns out he's been consistently cheating on me for the past 5 years.

My boyfriend and I have been having problems for a few months now, but we've always managed to work things out and come out on top. Last week he broke up with me, and said he doesn't feel the same about me anymore, and I'm not the girl he's going to marry.

I had kind of seen this coming since we hadn't been too great the past couple weeks, but I'm moving out and plan to be out soon. We have been living in the same apartment, usually with one of us leaving to stay somewhere else just to keep things civil until I am able to leave. Today I found out that he has been cheating on me consistently throughout our relationship. His best friend came to town and told me that there is a lot I don't know, and that he's been cheating on me for the past 5 years, with different girls.

I knew about small incidences, but they were always chalked up to a drunken kiss during a period where we had separated, but I have found out that was not the case. I'm devastated, and honestly I have so many emotions running through me, I don't know how I feel. Apparently everyone knew and no one decided to tell me, so I've been the poor girl who had a cheating boyfriend. Part of me wants to confront him about it and find out what happened from the horse's mouth once and for all, and part of me feels that would be a horrible idea. I get my keys to my new place on Tuesday, so I'll still have to be in and out of the apartment we share until then. I'm not really sure where to go with this.

tl;dr: Boyfriend of 5 years broke up with me and I found out that his drunken kisses with other girls were probably drunken one night stands. EDIT: I'm not sure if I should confront him about it and know the truth or just let it go.
