You say you stuck to everything they asked you to do - what exactly did they ask you?
This
There’s some context missing here, that might help unravel what’s gone on. Was it your son or DiL who you spoke to, what did you ask exactly, and ‘patient’ with whom or until when? How did you respond?
and this.
Loads of very interesting, honest and insightful replies here. But having read the whole thread the two questions above are what springs to my mind.
Everyone will have their own opinions and experiences but at the end of the day one of these two things is the truth:
a) The son and his wife are cruel and 'orrible (and this has been suggested quite often here)
or
b) Something has been said/done by OP which needs addressing.
Which is more likely?
OP says until baby came along her relationship with DIL was lovely. OP writes well and makes a good account of herself, but i can well imagine my xmil would have said all the same things and had everyone scratching their heads over what's wrong ...
Without both sides it's going to be very hard to get to the nitty gritty of this.
One last thing; when you say you are invited 3 times a week - who is doing the inviting? How is it done? Are both your son and DIL there when you come round?
See - my DH is a great one for, when his mum asks when they'll see us again (they have a long drive to see us) saying ohhhh yeah, yeah come over this weekend. And she goes ooh lovely!! And she plans it all out. And he's forgotten we were out/busy/got building work plans/he's working/he intended to do nothing at all 'cos he's knackered. And there we are 15 mins after the phone call and he's saying ''oh bloody hell i wish i hadn't told mum and dad to come this weekend ....
He does it all the bloody time. But he wont cancel. And then they probably feel we don't want to really see them because we're flying around trying to do all the things we had to do.
sorry that was so long. but this stuff is so complicated and nuanced. To sum up - You should talk to your son.
