How to let go?

It's been almost 2 months since we broke up. She hasn't contacted me at all. We didn't fight, we didn't argue but she ended it because we're spiritually not compatible as she said. She works for the Methodist church and I volunteer in my church. To have a long term relationship end because of religion, when both of us work for the church is difficult to understand. I truly loved her so every day she ignores me or removes something from social media just kills me.

She didn't explain why she broke up and I've been hopeful that she'd agree to calmly talk things through. My friends and family advise me to let it go, but I don't know how to do that. It's my first breakup, and from a 2 year relationship. I sent my fourth message since the breakup today. It's eating me up and it causes a lot of anxiety. Part of the problem is that I want us to still be on good terms so cutting her out is painful thought. I just don't know how to move forward when I think about her every day.
