@Youseethethingis you seem to have got this right.
No child chooses divorce, no child chooses having two homes.
They should be welcomed home, whenever, however, whatever. Otherwise it stops being their home.
I stand by what I wrote earlier, that I couldn't imagine a scenario where, as a teenager, my mum and dad wouldn't have welcomed me walking through my front door. My husband's mum and dad had a large family and are the same.
I wanted all our children to experience this, always. Even now, as adults they just arrive home although often now they are adults I get a text to say they are coming over. I just make more food or we get a take away.
This duel housing was never a problem a child created. That firmly rests with the adults in their lives. It's therefore our responsibility to make sure it affects them as little as possible.
This thread is sounding like a lot of you are considering having the children to stay rather than them returning home.
It's essential they feel it's their home. The second they have to ask for a drink, ask for a snack, ask to have a shower, ask to visit, it's not their home.
Children and their mental well-being is first. We are adults. Ours comes second. They are not children fir very long. Their future adult functioning depends entirely on their childhood and the bonds they make.
