The best thing to do brother is to agree with her.
If she is accusing you of something it means that she is willing to talk about it, but you need to bend, and bend a lot if your to win her back.
If she says that your a control freak, except the fact that your a control freak, that is how she is seeing you, accept it, and tell her humbly, "I want to change this, I don't want to lose you, will you help me change this". And mean it with all your heart.
If she says that your overbearing, than except the fact that your overbearing, that is how she is seeing you, except it as a fact and are you willing to bend to her?
If your fighting with her, your going to lose her. If you get on the offensive your going to lose her. If she says something offensive and you lose your cool, your going to lose her. If you love her, learn to shut-up because she has left because of something that you are not doing.
Don't come on here accusing your wife, she is finding fault with you, that is why she left. Eve left Adam and Adam accuses his wife. It's the old old story.
At this point you don't call her a liar even if she may be one. God wants to save her and your marriage. You don't want her to go further into destruction so she may come to her end, that approach is foolish. That is pity talking.
If she is accusing you of something, take it and humble yourself to wanting change and keep your mouth shut.
I remember a testimony a couple gave who were married and had children and he left her for another man. She got to praying for him. She believed what God hath put together let no man put asunder. Well, he would bring his lover home with him and she tell her husband, "I don't care who you bring home, your my husband and no man is going to separate us." That was her attitude. In the end, he got so sick of himself that he ran back home to his wife.
The moral of this story is that you have to get your word from God as to what to do and be fierce in your faith in the closet and be firm in what you believe God is telling you and at the same time be kind and gentle.
