I was a stay at home dad, could I take a woman for support?

I plan on taking her for whatever is fair to everyone, as of right now I let her come and go as she pleases to see her kid. She does not want to rais him but is ok walking in and out of his life. I deserve the same rights and support as any woman who was left with kids. Last night I was walking my son in the stroller and her drunk boyfriend aprouched me on the street talking to my son beer in hand. My son instantly knew who he was and started crying. I am sick of the garbage she puts us through and the way she treats us. I am going to take her for everything I am entitled to. Or she could sign over all rights and get lost. As of right now she pays our heat and gives me maybe 20 or 40$ here and there and conplains about it. The minimum i get for my son, she will not give me money for groceries but she will shop for my house but the wick she is still collecting helps with that. She wants to be in control of my household, she makes around 3500 a month and gives us barley anything and i have to argue and fight with her to get that. I am going to get her where it hurts, her pocket. Thats the only way ypu could get to a piece of shit like that. She cares about nothing else, she is part of this group. Her name ia carson gold or somthing like that. She pretends to care abput mens rights but not the rights of the man who raises her kids. She is more of a nazi then the lib she makes her self out to be. She is extremely sexist and racist against asian people. Our first birthday we spent together she slipped talking to me and called her son's father a n****r but has the nerve to say i do not care about brown people because i vote Republican..... No i just raised a brown person that wasn't mine though.... And i knew she was shit for the secound half of the relationship we slept in different bedrooms. I was only their for her son because he is a good kid and he needed me, She has never onced thanked me for being there for her kid when his own father was not.
