buddies? worth my time?

He is interested in -- not dating. If he wanted to date, he wouldn't be jumping in the sack with you. He'd be taking you to the movies. Don't automatically ume that means he is romantically interested. There is absolutely no way to tell that unless he says it outright. Many times the whole FWB thing ends up being a nightmare with someone having a broken heart. It's not a real relationship. It's someone getting the with NO strings. That's the whole point. It doesn't mean he wants to date you, and likely, he won't try to date you unless you has some miraculous turnaround. It's going to blow up in your face eventually. Save yourself the pain and get out now.
