My son and Daughter in law were married for 5 years and have two children.
The separated 3 years ago after my son had an affair. They seemed fairly happy, although I know daughter in law had/has a drink problem which may have contributed.
When I found out about the affair I told my daughter in law as I didn't want to collude with my son. They separated, my son carried on seeing the other woman (they are still together and have a 1 year old daughter.)
I supported my daughter in law, she came to live with my for a while and I helped her with money towards a new property. I see my daughter in law and the children once a week for a meal.
The children share their time equally between both parents. My son and daughter in law do not get on well. I don't speak to my son often, he says he feels betrayed by me.
My daughter in law is now expecting a baby. She plans to move to live with her boyfriend down south, quite a way from here. She plans to sell her house and drastically reduce the time she spends with her children.
I think it's a bad idea but have said she can stay with me on the weekends she comes back to see her children. Is this unreasonable of me, am I aiding her departure?
