Is there anyone that can advise on this? A and B are married. B cheated, got caught and was asked to leave then moved in with affair partner. B is now saying they want to move back in and there’s nothing A can do to stop them. There are kids involved and A is Sahp (and carer for one of the kids). The house is jointly owned - is there anything A can do to stop this happening?? A believes this would be damaging for the kids who are already very upset and confused and would obviously be bad for A too as they are still coming to terms with the end of a long and, what they considered to be happy, marriage.
I am neither A or B. I would really appreciate any advice from people in the know, or anyone that’s experienced this before.
