The implied threat is that she is making the case I should not be allowed to be their father.
She has cut me down and destroyed everything I hold dear, and the only thing left she has the power to hurt me with is my children. If it were not for my love for them, it would have been so easy to throw in the towel by now.
That's because she's grasping for straws. My guess is if you aren't mentally or physically abusive (btw, telling the truth about a situation is not mentally abusive... mental abuse is MUCH stronger... It's cutting down a person, destroying their ego... someone who destroys a child's ego, telling them they are bad or stupid), and my guess is you are not an alcoholic. She is grasping for anything to use against you. Make sure you date and take notes of everything in a journal.
I know how helpless you feel about your children. Unfortunately, we can't protect them from everything or make perfect lives for them.
P.s. Saffie, I lost your email address.... Blues, saffie is right. I know a guy whose wife did this to him (moved faraway so he couldn't see his kids). In the long run it only cut out an important person in their lives, severed an important relationship. And her life never got any better.... BTW, he eventually remarried a really nice woman he met many years later. I think she takes great care of him. They have no kids, but his kids now do visit in the summers.... and his XW did orignally want 100% custody. It all went into an ugly custody battle that he eventually concluded was getting too expensive and emotionally draining so he had to let go. I think it all came back to bite her in the butt. She only hurt herself and her kids. I'm sure they resent her for that. And he just had to accept and live with what he couldn't change.
There is no arriving, ever. It is all a continual becoming.
