My ex-husband, who has residential custody, has filed a motion against me for child support. I'm not trying to shirk my responsibilities, but I have one of our two children at least 4 to 5 days a week after school, I prepare and/or buy her dinner, I purchase her school supplies, birthday party gifts, etc. and take her almost everywhere she needs to be (doctors, dance school, etc.) He is withholding overnight visits right now until I "start paying him money". I would like to have at least one of the children approximately 3 nights a week to sleep over if the ex would permit it. The other child is 17 and quite independent. Although he provides the roof, there is little else he does for either of the two children.
