Let me start by saying I am using a throw away because I am sure my account is monitored.

I am in a huge bind. My relationship is falling apart with my S/O. We are 2.5 years in with a 6 month old son and her 6 year old daughter from another relationship. My SO is so focused on making things good with her ex that she is letting our family suffer. She is picking him up and driving him to and from counseling sessions to work on their issues. She goes out of her way to make his life easier to the detriment of our family and most importantly to the detriment of our sons care. He rules our lives, demanding meetings with her at his convenience where she will meet with him, or his family to decide how our family will do what he wants in regards to everything including pick ups and drop offs, how we will lie to his daughter to protect his image as he is going back to jail again, for the 2nd time in just over a year. My sons care has fallen to the wayside to the point where she is not even getting wipes for him because she is "to busy". That being said, she works 2 days a week and not even a full day at that. All of her aggravation with him is taken out on me, her daughter and our son. Sorry for the rant, but I know the mantra of Lawyer up and document. I have kept track of every verbal abuse I have been witness too, every physical abuse, but now I need to lawyer up. There in is the issue. I hardly scrape by as it is, paying for well over 90% of everything for a family of 4 as well as her ex and his well being if she is using the family car to drive him around. I am in Cali, and I know here the chips are stacked against me for just being the father. Does anyone have any advice or directions to resources in my area that can help me on a budget? I cannot let my son fall into her hands alone and be raised and treated like her daughter. I am also very afraid that she may try to take him and go "off the grid" as this is a lifestyle she idolizes. Any help is greatly appreciated.
