Hello. My question is regarding how to get a review for Child Support if Ex does not want to give up parenting days but is not home/overnight for our 16 yo. during most of his parenting days. This has been going on the last 3 months (since he has a new girlfriend). For example, this last couple weeks, he has not been home Wednesdays after school/overnight. The weekend he tried to say he messed up and thought it wasn't his weekend (he hasn't messed up weekends since he requested to change parenting weekends probably 8 years ago to match his second wife's schedule) so he then said it was ok for 16 yo to stay alone for 1-2 days while he left town Friday until Monday. It was 3 days (Friday Sat Sunday overnight) and he did not even ask me if I would be in town/home or if our 16 yo could stay with me.. ended up child had cellulitis Friday, got antibiotics from the doctor, dad left town, child stayed alone at dads, child's significatn other called me Saturday to meet at ER in a different town, apparently child left town to see significant other --bottom line thank goodness they were smart enough to call me, I met them at ER and they had to switch our child to different antibiotics due to possible MRSA as he was in bad shape from the cellulitis infection yadda yadda). Dad did not come home after being contacted about that. So child stayed at my house Sat and Sunday overnight. Child has been staying at my house on Wednesdays the last 3 months, a few of dad's Thursdays and some weekends of dads parenting time, dad doesn't even to bother to ask if child is at my house. I ask child if dad knows about staying at my house, child says no clue, dad never asked. Point is, I get that the child is 16, but still a child and should have had an adult with him Friday/Sat making sure resting etc. This is what prompted me to ask about how to go about on a review for child support since our child is now staying with me over 50% of the time. The last 3 months it's been about 80%. Child says to not mess with it because dad made his choice and it was not to be with child. It upsets him but says it's none of my business about dad and childs relationship and I need to not say anything to dad about what we talk about or what he says even when he is at dads alone overnight on dads parenting days and does not come stay at my house. Dad also will still not help pay for our oldest two children's medical insurance I hold, he is still holding something about switching our son from his car insurance to my commuter car and then he will start helping pay medical. But that's on another question.
