Why is her maintenance raised while I have custody?

After 17 long months since I filed for divorce, she left the house 3 months ago after giving her $10K. Last week we went to court and her maintenance was raised from $100 to $325 a week for the next two months. I have custody of our two kids and I don't receive a dime in child support. During the 17 months since I filed for divorce, she has disappeared for 120 days, getting support from me and various boyfriends. She doesn't want to work, she lives with a new boyfriend who has signed her lease, but she says she has subleased the house from him and pays rent to him directly $1500 plus $240 in oil bills. Anyone from Long Island know if the rent doesn't include the oil? I was paying pendente lite for 15 months. The judge said that the $325 is for two months and he told her to get a job. After that he'll adjust the amount of maintenance. She had traveled overseas at least 5 times that I know of, she's used to sugar daddy treatment and the judge told her to work even at McDonald's!! She doesn't have a H.S. diploma, never worked at least full time and I'm concerned that I'll have to support her for a long time even though she's supported with a live in boyfriend!! She lives in a much larger house than the three of us. I work full time, take care of the kids and she has them for only 4 overnights a month. In the stipulations she had mentioned that she would visit them twice each week, 22 so far, but she has visited them only 6 times. I'm afraid she'll show a minimum income in the next two months, so that I continue to support her. I feel very discouraged throughout this whole process. I won the forensic evaluation, got custody, she was abandoning the kids, I haven't taken a personal vacation for over 20 months, do everything for the kids and I PAY HER 29% of my salary which is higher than the 25% I'd have to pay for child support in NY!!! What can I do against this injustice? How should I prepare for the next hearing?? Her lawyer seems not to want to settle but to drag this for at least another year!! My lawyer always tells me to be patient. I think she works "secretly" and her income will never show up anywhere. I don't much care for child support, I just want this nightmare to end. Thanks for your advice!!
