OP, I really commend you for your down tools attitude and leaving these children, their mess, food and shopping to their parent.
Funny how many men push back hard when women want to do this.
I think you have come up with a solution that works for now, but be very careful.
It is EOW for now.
But as they get older, perhaps have children, you could find that with a parent that does so much for them they might want to be with you a lot more with their own children.
My friend found herself in that position last year.
Her partners daughter that didn't like her and was barely polite, decided that her father and their home would be a perfect weekend creche for her new child because her own mother wasn't very maternal.
My friends partner wanted her to be there to help him.
My friend had zero interest and took to going out 5 minutes after the daughter arrived to drop off the baby for 5 hours.
She had a few very very terse conversations with him that spelt out that she was not free weekend childcare for someone who struggled with anything beyond being cool politeness.
That she would be filling her weekend with single activities with her family and friends. She said that if she felt driven out of her home by this, he had two choices, spend his time at his daughters house childminding HIS grandchild, or they she could give her tenants notice on her house that she has.
His daughter didn't want her father in her own house, she wanted down time at home alone while her father did childcare at his.
He thought my friend was being very unreasonable to not want to share this with him.
It took two Saturdays for him to think it was too much.
My friend went to stay the night on both occasions with a single friend of hers.
Her partner was then asked for a 2 night with the baby at his daughter's house.
My friend told him to crack on.
It nearly broke him.🙄
The situation now is that he told his daughter it is too much for him and that actually considering how little she likes my friend she can't be surprised that she thinks it is a huge ask.
He thinks it is a huge ask of him too and that he wants to be a grandad that plays for a short visit, but childcare for hours is too much for him.
His daughter is very pissed off with him but that is not something my friend feels any sympathy for and is not interested in listening to him go on about it.
Particularly galling for his daughter apparently is that my friend loves her god childs little son and occasionally gives her god daughter a night away by staying and minding him.
Unbelievable!
If only his daughter had been open to being pleasant.
My friend never had any interest in being anything other than a friend to her, certainly not a step mother....she's nearly 60.
Her parents have been divorced many years and her father was single for a couple of years and she was used to it until he met my friend 4 years ago.
They are only living together 18 months, very shortly before his daughter got pregnant.
My friend is thinking that living alone is preferable and best see him when it suits them both and they are free
He can do grandad in his house on his own time.
She has quietly told her tenants that she will not be renewing the lease and just has to have the conversation with him.
She is so grateful she has her own home to return to. She is unsure the relationship will survive this, but isn't prepared for ongoing drama.
