Boy help

So I was talking to this boy on the phone a few days ago because we were studying for a test. After a few questions he stops and says “ivebeen meaning to tell you this for a while but I’ve liked you for a long time.” I asked him why he didn’t tell me earlier and he said it was because he thought I was gay. (I’m identifyingb as bi for the moment but ivebeen questioning if I’m lesbian for a while.) I told him my situation and told him I was bi but I didn’t know for sure. He then proceeded to ask me to the end of they year dance. I said yes because I was on the spot and I didn’t really know what to say...but I don’t think I really like him and I would much rather go to the dance with a girl... help please! 😭🏳️‍🌈 If you comment and you have a question about what I mean please just ask.
