Cps and the cops came to the hotel I was at with him and my kids and they took my kids after searching the room on a makedup clear cut straw in the bathroom. And ive been trying to get them back but the judge won't give me an lawyers because my EX husband makes to much money...I never see any of it he even kept all of our taxes and left me to live in.
