FWB (friends with benefits)

So i met this guy off the facebook dating. Common friends with one of my closer friends from awhile ago. We start talking he tells me he only wants a FWB relationship then eventually more. Two days later he comes over to my house and we just hang out for a little only kiss nothing else. A week later we end up sleeping together which was fucking amazing 3 hours. He ends up asking me if im still on the facebook dating and i said yes only because we are friends with benefits so i don't see a problem with talking to other people if that's what he wants. End up talking to this other guy which he was really cool. Well today i went over to lets call him Calvin we had sex like we usually do after he brings up the guys name i was talking to. He said how it made him jealous i was talking to him and that i should delete my profile. My thing is will we eventually date or am i just wasting my time on someone.
