I was divorced in 2010 and she was awarded spousal maintenance. I claimed adultry at that time and it was not proven even though I hired a private investagator. She is now living full time with the same person I claimed she was having an audltrus relationship with. How can I prove co-habitation? I have three adult children who all know she lives there. I can also bring the girl she is suppose to be living with to court and she will tell the truth.
