FWB....or what?

So this guy and I have been FWB for a while now. Sometimes it's hard to read him and I think both of us hold back when it comes to certain things due to not being sure how the other will feel. We know our "relationship" works the way it is now. I do have feelings for him but idk if saying something would change things and cause us to go in different directions...so I stay quiet. I just saw him earlier this week and took a chance and said couple of things in my mind. The next thing I know he asked me to come back over next week cause he wanted to cook me dinner and watch a movie. Usually we just go out for drinks then back to his place and hook up. Am I over thinking this or could he possibly want to move our relationship in a different direction?
