Firstly RETURN to your wife and family for that is the vow you took. Secondly, ask her to attend marriage counselling with you and pray for the right counsellor.
Thirdly, although WRONG, and she is wrong in hurting you, it is coming from a place of deep hurt and pain. I am not excusing her for this but that is a fact. So pray healing into her life and cover her with the blood of Jesus and refuse to listen to her words that break you down as they are NOT from the flesh but from the heavenly forces.
Fourth, work on yourself and ask God to give you a heart to change the things you can and to follow his calling. You need to step up as the head of the house and study what the word says about being a father/husband in the house.

Show your wife the mercy that Jesus showed us and NEVER GIVE UP PRAYING FOR HER OK. First things first.............return, for that is what God wants from you.

AMEN.
