Leaving my boyfriend...

I've been thinking and thinking of leaving my boyfriend of 6 years now that I'm pregnant is the right decision... I'm 6 months pregnant. So sad that I had to get pregnant to understand that this man is not for me. I don't regret my baby on the way but I really do wish I could of left him sooner.... Constantly being put down, treated like shit, being alone at home while he goes out every chance he gets to get drunk with his friends. He hasn't put $1 on towards the Babys needs. I thought about waiting till the baby gets here but I just realized that this is only going to get worse.. From being mentally abused to maybe even physically abused... Wish me the best ladies... Anyone going thru something similar?
