I'm so sorry to hear this but I'm glad that the truth has come out and you finally know where you stand. I have a dear friend, a pastor's wife,whose husband abused her and cheated on her. I was very close with her and could have never imagined he would ever have done such a thing. He left her and is living with his lover, the music minister in the church they had attended together. She is going through a divorce at this moment. I live too far to visit with her now but she is on my FB page. She puts on a brave face but when she can't cope she messages me and I told her to let it all out. Whatever she needs to say, her hurt, anger, tears, I'm there to listen and not judge. Often into the early hours of the morning we have talked. I'm heartbroken for her. And because my sister is going through the very same thing, it makes me even more empathetic. I hope you have a good friend that just...listens and prays for you, with no judgement. I know so many here are praying for you.
I find that usually when a man (a woman also) begins to change, refuses to talk, shuts down and is belligerent and abusive in a marriage, either emotionally, physically or both usually there is cheating going on. I fear this is the case for my sister. I hope you can find a new life and happiness now that you are free of this man. Hugs, and blessings, believing for better things ahead sister.
