My SO daughters (17 & 20) still go between our house and BM house every other week. When does this end?? The 19 year was away at college but decided to take time off, so now she thinks she’s just going to continue going back and forth every other week. Meanwhile, my daughters are still sharing a room and his have their own bedrooms that sit empty half the time. Am I wrong for wanting the 20 year old to live at moms?
