What do I do 😟😟?

I have a sneaky link (Friends with benefits) & this has been going on since June. The first few times we had sex I was alright with it. But recently I have been feeling some type of way. Like my feelings are getting involved. My friend kinda was a wingman and told him & he basically said he doesn’t want a relationship he wants to keep what we have, but also he said he doesn’t “know me enough, me trust me enough & that I have other men in my phone” keep in mind last year we used to talk. Than it stopped. And now we just have sex occasionally. But the last 2 times we had sex he said “I don’t know I have to think about it, because if it’s not me it’s gonna be somebody else” and when I asked him what he meant he kept avoiding the question. And we have sex maybe 3-4 days ago & he was asking to see what other men I had in my phone & trying to see my messages. The whole time I was there that’s all he kept talking about!! And I didn’t show him because I don’t ask to see his phone so why ask to see mine? And he got mad. & than asked how many bodies I had? He never asked that before Than for the first time he asked to cuddle with me? We NEVER cuddle. We did once and that was in June. Which was odd and when we were cuddling I got up because I knew that it was gonna make me catch feelings and he kept asking me why did I get up I told him to put on music to avoid the question. I didn’t wanna tell him because id feel silly/embarrassed telling him how I truly feel just for him to possibly say “I don’t feel the same way” When we were laying down he just kept staring at me, and didn’t break. But he kinda tried to have a heart to heart conversation after sex. He said “I’m trying to talk to you, I don’t get you & I don’t know if it’s me or you” I want to tell him how I feel & how it isn’t healthy anymore for ME because I’m catching feelings a little bit. I think I’m scared of saying it because I know he isn’t gonna feel the same way
