I must be unusual, I always looked forward to them (3) moving out. 2 did need to come back when falling on hard times but, moved back out within a few months. Young kids and adult kids are not the same. Been without any kids for 21 yrs. and that makkes me very happy.
Oldest DGD (23) has lived with us for 5 yrs. and is not the same as she lives her own life and very independent and responsible. We really only provide a room, she does all her own stuff.
I would have felt a loser as a parent if they didn't grow up and take care of their ownselves, not normal for a kid to stay home.
Good luck.
