I think I like my fwb more than he likes me.

I moved out of home 5 months ago with a good friend of mine, Dave. One month in, we started getting very cuddly and shortly after that we had sex. We do heaps of stuff together and we always have a good laugh, I think I'm in love with him. Recently, Kyle, another friend of mine broke up with his boyfriend. He has found comfort within my group of friends and has been talking to Dave more than anyone else. Living with Dave and still sexually being active with him, but watching him talk to Kyle more than me is making me jealous and I don't know what to think.Should I tell Dave that I like him more than just a friend? More than just a friend with benefits?Tl:Dr Fwb friend is still fwb, but I like him more than that and he seems to like someone else.
