Hello,
I am so sorry to hear that you are are going through all of this. I know that you are in the phase where the ex is trying to punish you for all that you have done to her. Trust me, I went through that phase. Everything was my fault and it was my fault she acted the way she did. However, this is just shifting the blame so it eases her own guilt.
I never wanted to inherent this mess either and there is nothing I can say that can make it any better. However, your statement is the best mindset:
But all I can be is a good man and love my kids.
That is the right focus. You can only control you and your actions can influence others. That's the best you can do on any given day. I do hope you stick at it and don't be discouraged. She made her choice and just as much as you have to live with her decision, so does she.
Have an awesome day,
(((Ready)))
