I was married to a man for 4 years. We had a son together. A year after my son was born the man got angry more and more. The breaking straw was when he hit my son for just doing something a baby does. The baby was just learning to walk and when he hit the baby's bottom the baby flew forward and hit his mouth on a stool. He then came to me crying. I held him close and got yelled at for "babying him".
He filed soon after and I can honestly say I'm happier than I was with him AND I got a wonderful little boy in the process!
