Symptoms consist of feelings, nervousness and...

Mini Rant: So I have a weird relationship with this guy on campus. He’s really attractive and I enjoy his company. We never really established what we were doing, as far as titles but it’s along the lines of fb/fwb. We are having fun which is something I am cool with. I don’t really catch feelings but lately I’ve been thinking about him more, get nervous when I see him in public, and even get excited when he text me. I rarely catch feelings and now I feel like this is going to mess up whatever relationship we do have. It’s college and I’m pretty sure he’s not looking for a relationship but neither am I. But Idk what’s been up with me lately. I keep telling myself that I just want him sexually but I really don’t know. I don’t know if it’s the sex that’s got me feeling like this but I don’t like it and it’s so random...😭😭😭😭

I am going to be so upset if I caught feelings for him. Especially if it isn’t mutual.
