DH and i are at our wits end and don't know what to do. DS has moved out of his home and left his wife and our DGD 3 years old, saying he needs space. He is back with us, he says he wants to work on his marriage and DS and DDIL have counselling arranged. But, we know he has been lying about what he does and where he goes, we have evidence of lies such as receipts for meals for 2 when he said he was somewhere else, plus other stuff.
We adore our DGD and DDIL ( she is devastated) and we are giving her all the support we can. She wants him back.
I'm so angry i want to throw my DS out, I don't think he has any intention of making his marriage work, and he has become a liar.
I have tried to confront him but he says nothing is going on.
Any advice on how to approach this mess
