I have a similar situation with my x and can only lend you this advice. It is about my children and what i did was just ask for them more often. Tell her that you are really hurting over not having the children and that you would greatly appreciate it if she would let you take them one extra night a week. I would be willing to bet that she would give them to you freely. I will not ask my wife for full custody of the children because i know that she will not give them to me. See, society doesnt look kindly on a mother that gives up her children. My x is so into image that she would never let that happen. I think that in some ways if you tell her that you just cant go on with out seing the kids, it justifys in their mind that they are doing a noble thing. It has worked for me and I now have the children between 3 and 4 days a week. My oldest of 7 years has just asked his mother and me if he can come and live with daddy, so you see you can get what you want with out going through the courts. you just need to be creative. I also agree my x would never give up the $3500.00 a month that she receives. But, like i said it is about my children and their well being. Just some ideas for you.
