Thanks for lots of differing views.
I started with a very simple scenario, maybe badly worded when I read back. I was then led into providing more and more details, most of which are irrelevant to the support I wanted. I do know lots about them as a couple specifically because I am not the MIL. I haven't been a part of this family much longer than she has! We were friends, she drove to see me, she confided in me.
I've seen a very different side of mumsnet which has saddened me. One is the assumption that all females must be in the right, that it is ok to justify keeping the LO away from her DF, that domestic abuse isn't considered to ever be female to male. I know many of SDIL's issues ( haven't shared, not relevant to the support I needed).
There is also the strong assumption that as the MIL I must be meddling. A suspicion that there must be something really wrong at this end. In fact we are just a fairly normal family ( just what is normal?) working through eventualities, doing our best (whatever that may be) with very busy working lives, two sets of elderly parents a distance away, 6 DC's between us and 1 DGD. Who ever teaches you how to be a parent, especially to adults.
I can't win. I am too involved for some, knowing too many details; not involved enough as we only see our DS in the school holidays. ( despite that suiting the couple in question, given the high involvement and prioritizing her own family before us and suiting us and our other DC's.
I will add that 'sneaking' in one of our DS's girlfriends, to the night 'do' at our DS's and SDIL wedding , (attended by SDIL's neighbors, great auntie twice removed) was perfectly ok with the bride at the event. It just couldn't be addressed prior for fear of her reactions.
We are trying to change our arrangements for the visit and will book a hotel.
We are also considering not going at all, so as not to make SDIL and us feel uncomfortable. We may just wait to see DGD when DSS has access.
He is at the solicitors tomorrow.
We always send cards and buy Easter/birthday gifts. We will of course carry on with that.
I started with a fairly simple scenario, asking for some help. I wish I hadn't. I felt much worse by the end of last night, than I did at the start!
