<human>: Give me a shortened version of the text

My boyfriend and I have been dating on and off for four years, with our longest break being for about a year last year. We met at college, and now I have a full time job at the college now while he finishes his last year of undergrad.

We've been fighting for the past few days, and in a moment of spite he told me he slept with two girls when we weren't together last year.

It really hurt me, because those are things he knows I never want to know or hear about. I slept with a few guys too, more than two, but I wouldn't throw it in his face to upset him. After I was clearly upset, he said he only told me that to reassure me he wasn't sleeping around and it was two girls from his hometown.

Now, it's all I can think about. It makes me crawl in my skin thinking about it, which I know is wrong because I had my own fun too. I know I'm acting jealous, I just don't know how to let it go. I struggle to get over these things and I feel like our relationship is only going to go down from here if I really let this affect it.

Should I just break up with him?
