Women will sometimes come back if she sees true change heart. I recommend that you get into counseling yourself with a Christian counselor who can help you with the issues that you understand are your fault. These issues will follow you all your life do if you deal now, whether or not your marriage is salvageable you will have a better starting point.
I don’t have the financial wherewithal right now to afford counseling. I’m doing my best to overcome my faults, but the counselor phase will have to wait.
