I have to divorce,please help

My hu*****and is such a jerk,he started having affair with a woman when I was pregnant with my baby. After I discovered it, he only said Sorry to me, but I can see they still keep their relationship currently. Everytime I fight with myself on whether or not to divorce him, but everytime after looking at my young baby's face, i just couldn't make up my mind.

He knows clearly where my weakness is, and his attitute towards me is getting worse and worse, I think it's time to get over with him now. It's out of my tolerant limit, I'll do whatever I can to divorce him, but for the sake of my baby, I need to find a good lawyer to help me get what I deverve both financially and emotionally.

Any recommendations on good lawyer in SF South Bay Area? Any recommendations on what I should do to protect myself and my baby? Thanks Thanks and Thanks!

Any organizations can help when he is violent to me? He has such a history before, I have to be careful.
