What should I do? What do you think about this???

Summary:

    I don’t know what else to say or do in the situation. I do not want this to be a personal attack or a judge of someone’s character, but I suppose it is on a level.
    I feel that I have bent over backwards to try and make this thing work for my son’s sake. I live in reality and know that life happens and that none of us are perfect. I will claim responsibility in my part in this relationship and I admit fully that I have not been completely innocent in how I have handled or approached situations that have come up between myself and Other parties involved.
    I am only writing this today for the fact that I feel I have tried to address matters that I do have a right to have a option about and nothing is being taken serious. I have reached out and asked for help from him, I have tried to voice concerns of violence in his house, I have tried to get a little respect and set up boundaries to better organize my life while working 3 jobs at one time and he was not of any help, nor was it of any of his concern.
    I have asked simply for the following from him:
-- Argue and handle his personal relationship with his live in Girlfriend when the children are not around to witness the actions and reactions during problems in a relationship.
-- I asked of them to stop the move in and out game or end it completely. I asked because at this point the cops had been called for violence inside the home and other party had my 12 year old daughter packing another parties things for her at 2a.m. or so.
-- To respect my time and give me 24 hour advance notice upon wanting to take his son.
-- Have better communication and discuss such things as to when he would drop Joseph back off, or taking our son out of town.
-- I also gave other party $100 out of my food stamp card for the time that Joseph had been in his house during a month, the entire 4 or 5 months that I actually received assistance.
    He has hindered me from getting any assistance for my children because he does not pay child support. I have excepted it and worked 3 jobs at one time to support us after getting cut off for food stamps because I “made” to much. I have given and given as much as I can. I have tried to make this work and benefit all parties, but mainly the Children.
