...good luck & hopefully your kids will appreciate your efforts when they are old enough to 'get it'
Alas, this comment reminds me of a sad story, for what it's worth...
A friend of mine wanted a divorce 30 years ago -- he had two very young children at the time. His wife (enraged at this turn of events) offered to let him have the house and forgo child support if he'd give up all rights to the kids. But he loved his kids and refused the deal.
A year or so later she moved them to Florida with her new spouse, fought tooth and nail against his every visit, and in the meantime filled the kids with every negative thing she could make up about him. Despite a costly long-distance battle to see them, and the judge's eventually ordering the ex-wife to bring them to court "with their suitcases packed," he couldn't overcome the handicap of her influence. His kids never did grow "old enough to get it."
His daughter does not speak to him and got married without his knowing about it. His son doesn't return his calls. It's incredibly sad to see his eyes tear up when he talks about it.
Sigh. I don't mean to be a downer here, but we haven't yet taked about what the children will think about this move. It seems that any divorced parent who loves their kids might want to examine every action from their point of view. And this includes thinking about the long-term ramifications of pissing off the other spouse.
Yes, he or she may have done terrible things, may have hurt you, may have been evil incarnate. But a parent has tremendous power over young children's minds and the attitudes they'll carry for the rest of their lives.
One might want to think long and hard before giving an ex-spouse the ammunition to tell a kid that "you can't (do that / have that / go there) because Daddy doesn't want to pay for you anymore."
