This does not justify the behavior, but allows for compassion and to see where the behavior is coming from. It has made me realize how my ex has put my son in the position of "you don't love me if you love mommy." Son has developed a protection mechanism for himself. His biggest fear is losing daddy.
Awww, Free One.
This is such a hard concept to embrace. I think it's so great that you are able to look at it with understanding (and compassion).
I'm a stepmama, and my stepdaughters' Mama struggled so much with my presence (still does to an extent).
Without pushing my agenda too much, I've tried to express that it's OK to love both parents (and me even).
I think that just because your ex is pushing his black and white thinking (if you love me, you hate mom) that you can push your own thinking, without expressing Dad is "wrong".
He's allowed to love you. He's allowed to love dad. He doesn't have to pick.
Encouraging his relationship with his father while encouraging his relationship with you.
It's so hard, I know.
