How to tell him the truth?

Okay so I’ve been seeing this guy for well over a year. We use to be friends but it just turned into a sexual relationship. I don’t see him often because we just live two opposite lives. I’m still in school and he has a full time job. So we don’t often see each other but when we do, we just end up having sex because that’s what he wants. But the last time we had sex, I think he felt really bad because he kept asking if I was okay. Then he made actually cooked me some breakfast and sat with me to talk about future goals. Like he asked me what I wanted to do, if I wanted kids, and ect… I lied about not wanting kids or a husband because I didn’t want him to have any idea that I liked him. I guess I could say it was just me guarding myself to not get hurt but I’m hurt anyway just being in a nowhere relationship. So lately I’ve been regretting about lieing to him. Even if I told him the truth, I think it wouldn’t really change anything besides the fact that I may of lost a sexual relationship (even though that’s a good thing). I’m really scared because before I cried because I didn’t think I would see my friend again and now I’m crying because I messed up everything. Like I knew before hand that I had some sort of feelings for him and it just got out of control but it was the only way I could see him. I’m really confused and I feel very boken up about the situation. So what would be the best solution to this problem?
