Hey sweetie. Love that post from 123Gwen. Im sorry your xh is being an as$. Here's the thing..who cares if he blames you? You know your truth, so does your daughter.
You want to know why he is blaming you? Because it cant be him. If its him then what will he do? They cant handle that. So, they lashes out.
M, you keep having expectations where he is concerned. That will only hurt you. You expect him to act like a normal person and he isnt.
He did what he did. You cant undo it. You are getting hung up on words from someone who is not of sound mind. In his head, it didnt work out between you.
I dont agree with sending him anything. He cant hear it now. You will just be spinning your wheels.
You need to be there for your kids. You need to let go of him and her. They dont hold any weight in our life any longer.
Do not allow either of them to control your headspace.
