Wrong for being upset?

I talk to a guy from my church. He made feel very special and reminded me of my worth. I was skeptical because he way older than me I’m 19 and he 27. and also talks to someone else from the church but he doesn’t really consider them in a relationship because she would go days without taking to him etc just didn’t really seem like they together .. we went on dates long story short we went to a hotel and stuff happened (we did not have sex). The next day we felt really bad about what we did and decided to end it .(No one in the church knows about us. )She came back from her vacation and he told her that he cheated and she instantly forgave him and was willing to give him another chance. He then Called me ask what he should do and that he wants to give it another try with me but i told

Him if wants to be with her then he should stay. He then says he would give me a boyfriend experience but that’s CHEATING again. I’m very upset that he’s back with her. I feel like i waisted my time like what was point? Idk how to feel
