How do I get over my ex?

Anonymous
I'm saving myself for marriage, my ex who blocked me and broke up with me has recently broke up with her rebound boyfriend after 2 weeks. She gave him head and she was eaten out by him. I thought I blocked her on all platforms. But she emailed me saying she wants to talk and wants a future with me in the distant future.
She was in this relationship with this guy for 7 months vs me which was 2.5 years. She almost has nothing bad to say about him, but she says I didn't communicate with her enough and I didn't tell her she's pretty enough and she says that might have been because it was a long distance relationship and I feel cringe when I compliment people.
The reason why they broke up is because of religious differences, which to me didn't really make sense since our religion is against sex before marriage. I thought I was over her and I feel like an idiot for replying. I've been lonely and before I've had a crush on a family friend, and she's almost on the other side of the spectrum and she's a really pure person, she's so down to earth she's an extrovert which helps because I'm an introvert. And it kind of balances. She knows my face but I haven't really said anything to her in person. I dmd her asking if she remembered me and she does and I just spoke to her but very briefly. I feel like I'm at a crossroads.
Should I become friends with my ex and possibly get back together with her?
Should I try and pursue talking more to the other girl?
Or should I not do anything and just forget about girls all together?
Any advice would be appreciated
