There's this guy

sorry it’s long-ish

There’s this guy who I’ve known for about 2 years (we work together), we had a bit of an exclusive friends with benefits thing going from last november till the start of this march. We ended after an arguement and he really upset me with what he said. Yesterday we got talking again, went for coffee and ended up fooling around. Do you think he want’s to start it again? also I would only want it if it was exclusive but I don’t know how much I can trust him anymore, what do I say? and do you think it is a good idea? I still find him really atractive but I don’t know how he really feels! any advice would be great!
