Child abandonment question
Okay, the scenario is, my wife and I have been having trouble for a couple of years. On May 1, 2010 I found a house to rent a room and moved out. I have over the past few months gone over to our house to help with various yard work, including going over while her and the kids were out of town for a vacation weekend. We are filing for divorce at this point, but she has told me she will not ask for child support, she makes $150k+ per year, I make 36k. As part of the divorce paperwork, she wants me to sign a quitclaim deed on the house, telling me that she will give me 25% of the proceeds when she sells the house when our youngest, (16year old), gets out of high school. She stated that since I have abandoned her and the kids for three months now, if I don't sign this, she will try to get the courts to rule that I get nothing in the divorce.
Now, here is my question, since I left, the kids have had birthdays, I paid out of my pocket for the youngest to get a cell phone and I paid out of my pocket for the oldest an up-graded video card for his computer, I have also paid for lunch and movies on the weekends, (from time to time). Does she have a leg to stand on that I have "abandoned" the kids?
