My ex girlfriend is getting married. I've not been in contact with her for 2 years, I'm working on my mission, I lift regularly. And I already knew about her boyfriend.

Then why does it hit so hard knowing she's going to get married. I guess I already know the answer.

My question is, I know she is not gonna be in my future, and I'll probably not even care in some years. But how do I get over this crushing feeling in the short term?
