Should I change gyms?

I've been working with trainer for months and have had excellent results. The problem is that I have slowly developed a crush on her. I cannot believe this has happened as I am happily married with children and good, full, active life. What boggles my mind more is that I am female and have never ever been attracted to another woman. This trainer is a body builder, so has a masculine physique. We had a great rapport and went to lunch and texted a lot. She even seemed to like me at one point, calling me affectionate names, complimenting me, making me feel so attractive. I'm realizing now that she was probably just friendly to keep me coming back for the money. I guess I mistook her friendliness as a real friendship and somehow let myself fall for her. I told her I'd become attached to her but is still friendly and says she'd like to get together for lunch or whatever sometime yet she doesn't respond to my emails. I am so confused as I've never been in a situation like this before. Should I be embarrassed over this? What if other people at the gym know I have a crush on her? By the way, I stopped training with her because I couldn't afford it anymore, but I still see her at the gym and talk to her sometimes. My biggest question is should I change gyms?
