Alima.
My heart goes out to you, we are in a similar position.
Our daughter came to live with us last year, had enough of husband lying and running up debt. She moved back into her home around February time and SIL moved to a flat. Her divorce came through only last week but the financial side still need sorting out. It's the new mortgage thing that's the problem and waiting for a judge to make a decision to be able to finally get to an ending. Hopefully she can stay in the house but it might have to be sold. We are waiting for court decisions now.
The thing is we did everything possible to help and the split has been 'fairly' reasonable , which is a blessing. Certainly had a few ups and downs but they are hopefully getting there.
The reason I am posting is to say they have both found new partners, early days I know but it has brought a new dimention into the mix. I have 'loaned' them money because it could so easily be a case if both incomes were at some stage joined together their income will most certainly be higher than ours. So many variences to think of.
We will all move heaven and earth for our kids but I have found that months on there has been so many twists and turns and scenarios we never even thought of that it is wise to try to go with the flow and at the end of the day there are so many things crop up it is difficult to state categorically, well this will happen, that will happen.
Yes my daughter could have stayed in the house but her thought is whatever has happened they both share the love of our DGD and she has tried to keep things amicable and doesn't want that to change. It is a personal choice and one they will have to make.
All very upsetting, I wish you all well and I hope things get sorted soon.
