Go with my gut feeling or wait??

So guys I’m a little confused both with myself and the person in this story... ive been talking to a guy since March and he is great and we HAVE talked about becoming more along with just being FWB. I’ve known him since middle school but things kinda changed... we act like a complete couple like as if we were dating for years. Lately I’ve been going through a really rough time at home along with having to move out cause my mom doesn’t want me around.. so am I just depressed and overthinking his actions? He treats me like I’m his girl but then said “I hope you aren’t hoping I’m gonna change my mind one day” after saying he doesn’t want a relationship. So since that I’ve felt maybe he just says nice things to have sex with me.. I wouldn’t mind having just sex and nothing more but just tell me that.. idk should I trust my gut and leave or give him a chance to own up and figure out if I’m really what he wants.. I’m give more details if asked for them.
