CONFUSED

I'm not the type to settle down and be on a relationship, I used to be in a 4 year on and of toxic relationship but it ended in april. So I after that i haven't felt the same, I haven't wanted to be with anyone and just have some fun but I met this guy and it began as friends and now it's a benefit thing, and latley I've been feeling like maybe I could be in an actual relationship with this guy but then I have days where I don't even think about him and I completely forget he exist (LOL). I just don't know what could be possibly be making me feel these ways
