If you really like him , you should... if you don't, don't make him wait for nothing

I say date him. It's not a marriage, if you don't like it you can walk away with no hard feelings knowing you gave it a shot. Just because you're "In a relationship" doesn't mean things have to dramatically change overnight. Go for it and take it as slow as you're comfortable.
If you don't, you'll just be stuck wondering.
