I want to break up with my “boyfriend”

So I’ve been dating him for almost six months, and by dating I mean texting periodically and only ever seeing him at school. When I started texting him I thought it was going to be something short and we went on one date after like a week of texting each other. It’s the only real date we’ve been on, and after it he was calling me his girlfriend and I figured he was sweet and cute, so I just let it happen. By this point I don’t know what to do since I never see him cus I’m always working

I don’t really expect a response to this I just really needed to put my feelings and thoughts out there.
