Screwed by Southeastern Oklahoma

I was married to a woman that couldnt seem to stay out of other mens beds. We had two wonderful sons. She is so bitter to the fact that I am now with a super woman that the boys when they got to meet her just thought she was great. The last time I seen them was at my house for christmas about 5 years ago and they wanted to come stay the summer with me. From that point on, her lies got worse. Well I guess you know what I'm talking about. I got behind a few years back do to some medical conditions and with the intrest wow the state makes sure that you can never get back on top of it. In one year it went from with intrest 9k to 19k now you tell me how the hell that happens when you havent missed a payment. My oldest son is now married for a year now and he's twenty quit college and I have requested a hearing five times to have him pulled off the support but they wouldn't give me a hearing for that. What is a man to do. Right now with as much as they take out if it wasn't for my fiance I wouldnt even be able to live in a homeless shelter. I literally make enough money to pay for my gas in my motorcycle to get back and forth to work. Now they are wanting me to pay 150.00 more a month and what for because of her lies the boys wont have anything to do with me. People have been saying for years it will all come back around on her. Well I'd like to know when beccause I have been hurting for years she got me the only way she ever could. She took my boys away from me. Well if anyone has any suggestions for a broke dad to fight this it sure would be appreciated. I just cant do this anymore. The state of oklahoma is the biggest crooks I've ever seen.
