Help understanding a break up
I've been broken up from my ex girlfriend who is a single mother for 2 months now, we've had very little communication. I've been told that the reason for the split is that when we got into an argument I questioned why she went out two nights in a row and who was taking care of her kid when she was hungover. (Huge mistake because I said it angrily.) I've apologized sincerely because I know she's a good mom, its one of the reasons I'm with her and I was just angry that she didn't tell me she wanted to have a girls weekend.
She says she can't forgive me for what I said and wants nothing to do with me. I love her but I don't want to bother her. Some days I hold on to false hope that she'll realize that I'm just a human and I make mistakes and other days I think its best to move on. She knows my feelings because I acted like a goon after we broke up and text her on average twice a week. I just would like advice on moving on because I'm stuck in a rut of hoping for her to come back and grieving for losing her.
