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

Me [22 F] and my LD BF [21 M] have been together for 8 months. He cheated on me once, and we've broken up twice. About a month ago I noticed he was being very distant and stopped saying that he loved me. When I snooped, I saw that he was using his OK Cupid and I was pretty heart broken. I called him out on the fact that he was shutting me out, never mentioning that I saw he was using his online dating profile. After a couple rough days, he said he loved me and I saw that he stopped using it. Lately it seems like he's been shutting me out again and yep, he's using his OK Cupid again. I'm just... heartbroken. I really want this to work, but I don't think he's committed to me. Should I break up with him?
