When my bb was near 6 months' old, I thought of divorce. Men are selfish and they will not sacrifice their time to look after their children (still addicted to their computer games).
I understand your feelings because at that time this needed the greatest courage and support from my family and friends. The only fear is that my 99 (always claiming that she is capable of baby sitting instead of my maid) tried to seize my BB.
If you are breastfeeding, the chance of getting the bb is high.
Tell frankly to your parents how your husband has treated you badly and convince them by considering :
How old are you ? Are you prepared to live in the same fashion for the remaining years of life ?
Will BB have a happier life ? (when bb grows up, she won't be happy to see her mother always weeping and it's difficult to control your emotions either)
Your parents, friends and BB should understand how hurt once you were and why you have made such decision.
Be prepared to move your bb to a safe place if you discuss separation with your husband.
Your money deserves a wise spending. Not to be spent on somebody who is extravagant and does not love you. It should be used on your bb.
