Matt, you keep doing the same thing over and over expecting different results. That's just craziness, ya know?
So, you cant trust anything that she says. You knew this already. She aint who she was. That's just the way it is. The sooner you accept that, the better off you'll be. You dont get her because you arent in crisis.
So, first you tell all the ways your wife has changed her mind over and over, then you say she will never stop or change.
Matt, she is crazy. She may change, she may not. The only person you have control over is you. That's it. Not her, not her father. You have to let that all go or you are going to go round and round and round.
Accept what is, even though it succks. Let go of the rest. Protect yourself and your children as best you can. Understand that no matter how many times you write or think about the situation or her or her father, it isnt going to change right now.
Be the man you want to be. Be the father you want to be. Leave her to her cray cray. Just get out of the way of it. You dont want to get any of it on you. .
Time to let it go, Matt. That is the way out of this for you. I know its so hard, but, it is what you have to do in order to come out whole.
You can learn to trust again one day. But I wouldnt worry about that right now. You need to take back control of your life. You are giving it all to her.
