Ok, sweetie. Most of what he said, we have all heard in one form or another.
Right now your focus has to be on protecting you and your kids however you need to.
Put your marriage safely in a box for now. You need to get yourself good and strong.
Try to stop engaging with him when he starts talking about the marriage and divorce.
And yea, the never changing his mind thing....we know he already did that once...
Sweetie, it really is best for you to take care of you and your kids. Keep contact with him to a minimum. I know you are afraid if you do that he will pull away completely. But the truth is that he really needs to work this out on his own.
When you talk at him....he is hearing blah, blah, blah...she isnt hearing me.
Oh and there is always hope....until you decide there isnt.
So, tell us more about you. What are some of the things you need to work on?
