it's not daddy issues

So I've been dating this guy for about a year now. But the first six months we didn't tell anyone. We were just having sex. We probably went on 4 dates in six months, but it was okay but we knew that we only wanted sex. So now it my first year of college, and I had sex with someone else and of course I told him because I would want to know. All of a sudden she told me he was in love with me and blah blah lol now we told everyone. But the thing of it is.. i was 18 and he was 32. I love him so much . And no, I don't have daddy issues. But it's weird I'm about to be 20 , and I don't know if it will last last because of the 13 year age gap. I need advice y'all lol
