Should I Get Back With My Cheating Boyfriend?

I found out my boyfriend got drunk and slept with another girl yesterday and a lot of crying later I broke up with him even though I still loved him. Today he came over to my house and was crying saying he’s really sorry and promised he’ll never do it again.

At first I didn’t believe him but he said he’ll give up drinking forever if we got back. I wanna get back with him too but it really hurt when I found out he cheated and I don’t think I can take it if it happens again but at the same time he said he’ll give up drinking so that’s a big sacrifice. I don’t know what to do, If you were in my position what would you do?
