Fuck buddies but??

I am currently just sleeping with someone, a friends with benefits type situation. But lately it’s been really different, he made a comment about him liking me and then denies that he does when I bring it up. He came to my house and said he just wanted to ‘chill’ and watch a movie, and to not have sex, which he’s never said before. I went out with one of my girlfriends last night and when I got home he was questioning where I was and who I was with, I do have feelings for this guy and he doesn’t know, but I can’t help but feel like he’s slowly starting to care?

It’s quite confusing and I really need some help.
