I think first of all parents that make false allegations should absolutely be prosecuted, that being said I believe parental alienation exists, not saying in all cases and yes I believe it can be used as an excuse at times but it DOES exist.
And honneslty Liz, the Family Law person drove me NUTS. I was so happy when the daughter of the man who kidnapped his children put her in her place....I wanted to do that through the whole show. Couldn't believe she questioned Dr Phil as to why parents would actually use their kids as a pawn, I've seen it time and time again - they're mad at eachother and the divorce becomes a competition to try and hurt the other party more...including the children digs deeper, therefore gaining more ground.
People should put their kids first, not just say they do but actually put them first. And the more you keep the kids out of the divorce the better off their are. Bottom line being a "bad" spouse has nothing to do with being a bad parent, the are in my mind completely separate issues.
