I highly doubt you broke up over a stupid fight. your relationship probably had other issues that weren't being address and the fight seemed lke this was the reason. You shoukd of thought before talking to him and hooking up. You need to decide if you have blinders on right now and not see what else was going wrong in your relationship or actually go through with this.

You have now entered the friends with benefits stage... Where your relationship isn't defined but you're seeing and having sex with each other. Either you need to define your relationship or keep stringing yourselves along until one of you gets tired and moves on.
