This will be long so apologies in advance
I need some unbiased advice about what to do about DPs mother
She has never taken an interest in our children, ever. We have DS1(6), DD(4) and DS2(8 weeks). She has met DS1 maybe 5 or 6 times, DD 3 times and never met the baby or even seen a picture of him as far as I'm aware.
Nobody has ever stopped her (until me maybe a year and a half ago) she just never bothered. She never rang or text asking to see them or asking about them, DP would take them to his mums and she would go out. She just didn't care, so has never been part of their life.
So every now and again DP gets what I can only imagine is some kind of prang of conscience and says he wants her to have a relationship with them, a few times I've said ok do whatever you need to do but she always let's them down. He invited her to come to our house to spend an hour with the kids on a Sunday each week, she came once then disappeared again. So he tried again a few months later, she came twice then never again. Then he asked me to try again and I said no. So he said to her that she had to build bridges with me now, so she text me asking how everyone was what the kids were up to etc, I replied and she didn't, never heard from her again. This was last year.
So now we've had DS2 she's asked whether "she's allowed to see this one"
you were always allowed to see the fucking other two!
DP now won't let it drop and wants to try again. I've said no and I'm not willing to back down again. Why the fuck should I?!
DS has been quite a poorly child and was in and out of hospital with respiratory problems when he was a baby, she never even called to ask how he was. DD had meningitis at 3 months old. She never asked how she was. Fucking meningitis! Even the window cleaner asked for updates! But her grandmother? Nope!
She clearly doesn't give a shiny shit about them, so I don't get what DP thinks anyone will gain from forcing it.
I don't want her in and out confusing the kids and upsetting DP. And he does get really upset, which is hard for me to see, but she just isn't a good person and I can't change that, and nothing he does will change that. She doesn't bother with DP either, no phonecalls on his birthday or Christmas, nothing. I am very very close to my mum and can't even imagine how much that must hurt, So I just don't want to let her hurt anymore people that I care about. Again!
DP is adamant he wants his mum in his life. But I can't make him see that she doesn't want to be there!
What can I do/say? Just how do I handle this? We've reached a bit of a stalemate
