PLEASE ANSWER I NEED HELP BADLY?

This summer has been a bore and I had nothing to do. So I was on facebook alot and everybody keeps talking about fake profiles and I thought it was funny. So I was talking to my friend about it and she told me she has a fake account secretly and I was like I will make one just for the fun of it. So I made it uploaded so photos off of google. I added some kids from my school and they were dumb enough to add someone that they know nothing about. Anyways some people called me fake so I blocked them so they thinked I deleted it and now I hear that everyone was talking about it at the skating rink on Friday. LOL. They have nothing better to talk about. Plus people who make those fake profiles were judging mine when they do it too. Anyways this guy from school who I thought was a total doushe bag. Sent me a msg by mistake and I was ????. Then we started talking. Then he gave me his number and I texted him from yahoo. Then the next day from the time I got up till 1 in the morning we were iming each other for over 13 hours straight. You would think we would run out of topics to talk about. We talked about music,tv,sexual experieces(LOL)(I never did anything with a boy, I never even kissed one) (but he did some things),the future, and then I asked if he liked me and he said yes but he wouldn't hurt his girlfriend. Then I told him he was really flirting and he said he feels really bad for it and he doesn't know why he kept going and I was like don't feel bad and stuff. Then we talked some more and I am starting to crush on him and my brain is like are you crazy but my heart is like you totally liked him since health class don't lie to yourself.Plus I never realized how sweet he is and so caring and down to earth, he was like a different person.Then today when I heard that beep on facebook message my heart like went racing (really weird) So Yeah I like him he likes me but not me(if that makes any sense). So my question is should I keep this charade or end it before it get's started. I don't want him to be all confused.
