Hoping for more

We’ve had sex a few times but under a FWB deal. However we are attracted to each other my feelings stronger than his. He says things like sometimes I see us together other times he doesn’t. I’m so confused. I really wish we can talk it out and see where it could go.

I also can’t help but feel like because he and my sister are no longer friends and she doesn’t support us being together pushes his decisions to not try or give me a chance other than just FWB
