Pyrite: Eye of the storm?

[MrBond]

"Explain to me exactly how introducing her new partner into their lives as the constant male figure who has replaced Daddy is good for the children. "

I don't need to. You could have a stack of statistics and facts and it won't make a lick of difference. You don't seem to get that. She is going to believe what she wants to believe same as you. You have to start seeing things from her POV if you want to have a chance.

Right now she is seeing it as introducing the kids to someone who LOVES HER and RESPECTS HER and MAKES HER HAPPY. She feels like this stranger is a better alternative for your children than their controlling dad. You keep fighting that, but that is her perception.

I don't see where she actually said she was replacing you. She just wants to show the kids the person who makes HER happy.

I haven't seen your list of things and especially actions that would make her happy. I mean, you still haven't changed, so why would she even want to go back to the same situation? You have to give her some kind of reason why you're the better pick.
