What do you think changed?

I’ve been friends with this guy for about four months. We are really just fuck buddies tbh. That’s kind of our thing just a sexual relationship online. Every day he would be really horny and we would sext and such but the past few weeks he just talks to me. We just have genuine conversations about our day and stuff. For the last four months he really wasn’t interested in that but idk what happened. Like before he wouldn’t care if I didn’t text him for a few days but the other day he told me it makes him sad when we don’t talk for a few days and he’s never horny with me anymore. Before we never talked about anything but sex...

I’m just confused on what happened. He even told me a while back he only wanted a sexual relationship with me I told him I wanted to same and nothing else but now he seems very different and always checks up on me or asks me how I’m feeling emotionally and constantly messages me and before he never did that.

Do you think he maybe has feelings for me?
