I needed to reblog your post because I find your story so interesting. You invested allot, even your own self for the relationship. It's sad that things didn't work out as you expected, I don't want to blame you neither do I want to blame your ex.
But my kind advise is; you should know and understand the role of a man in a relationship. A man isn't weak, you can't be weak and lead as expected. Do you have reasons for not scolding her when she goes wrong?
You don't have to be violent on her but as a man you aren't supposed to be quiet when things ain't going right in your family. She felt you were incapable of your position as a man in her life but I still don't support her act.
The issue of whether to go back to her or not, the big question is do you want her? Do you still love her? Most times a broken relationship like this is very difficult to amend.
If at all you love her so much, this means that you'll have to do allot of work.
Observe her, check for changes because she might not be the same. I personally find it difficult to go back to a broken relationship but everyone has what works best for them.
You can even decide to go back to the friendship with her so you'll pay more close attention to know her like from afresh.
I hope things work out fine for you, in all, prioritize your peace man..
