So you think a child who has to bury their head in a pillow every night just so that they don't hear their parents fight is better than the parents divorcing, the parents then get along better and be alot happier around the children? I think that you should have done ALOT more research!!! My life was much better when my parents divorced. What kind of role model are you for your child letting them think your spouse can yell, and treat you like dirt? Do you know what kind of damage it causes when you listen to your mother call your father names like "useless" "stupid". Children are products of their parents and it does tremendous damage to a child's self esteem. My life was so much better when my parents divorced. I wish that they would have done it alot sooner. I saw both parents everyday, it was wonderful because my dad wanted to be with me because HE wanted to, not because my mother made him. They ended up becoming friends. Both are remarried and we celebrate all family functions together. I cant imagine what kind of life i would have now if i had that for all my years at home.
I would NEVER want my children to stay in a marriage just because they have children. It really doesn't benefit anyone. Your children know what is going on. Do you want to be that kind of role model. Do you always want to be unhappy around your children and they can tell. They can see the circles under your eyes. They are not dumb.
Unfortunatley some families have bad custody fights and that is the part that is much worse, but pretending to be happy, what kind of life is that for everyone including your children. Doesn't everyone just want therir children to be happy when they grow up. Staying in an unhappy marriage doesn't set a good example. A son seeing their father beat up their mother. Well children learn their behavior from their parents. Staying only teaches a person that they should stay and take the abuse. It also teaches a son that its ok to treat women like that. Same for girls. Do you really think that's the right message?
Unless you have been through it either as a child or have been divorced yourself, no research can tell you what it's real affect is.
