FWB of 10 years

I have had a FWB off and on for 10 years whenever we were both single. He is a Leo male hard to read and I am a Gemini female who is all over the place. I never met any of his girlfriends and up until this past year I had only met one of his guy friends. However, the latter part of 2017 he has started introducing me to more people in his life. In the last 3 months he has invited me to hang with him and his guy friends, he offered to take me on a trip and is becoming more affectionate(when drinking). i even overheard him bragging to his buddy how I got a raise and was advancing at my job I am starting to think he wants more than just sex, however the last 3 weeks I haven't heard from him at all. I am so confused because I think I like him as more than a FWB.

Help all my personalities want to scream

thanks
