Should I get in contact with my ex girlfriend?

So, a couple years ago, I started dating this girl. She was actually the one who made me realize I like women and that I was a lesbian. Her mom was very against her daughter dating until after high school, and especially against dating other women. So, we kept it hidden. One day, she came home early and caught us making out and I was sent home. I was told by her mom I couldn’t see her again until we could prove we were just friends. At the time, I couldn’t do that. This was my first love, and being told I could hug her, or kiss her really hurt me, and it hurt to be in contact with her, but not be able to be with her. One day we just stopped talking all together. Recently, I’ve been think about her a lot and wonder, should I reach out to her and talk about what happened between us, see if we can still have what we lost, or let her move on with her life? I know through a mutual friend that she was upset with me because she thought I was only with her for the “advantages” of being in a relationship. I just don’t know if I should let her be mad at me for how thing ended, and not be 100% at her mom, or try and explain things to her and how I felt and why I stopped trying because it hurt me.
