Short version of a very long story is that my ILs were pretty awful to my DH as a child and young person and he's had to have therapy for issues relating to abandonment etc. He had a really rubbish childhood including his DM telling him & siblings regularly that having children had ruined her life. She left often to live with a new man but then came back over and over. There were times when DH was a child (under 10!) that she would say 'don't tell Granny I am going to stay with X as she wouldn't understand' etc. I know all this is true as we have been together since school.
We now have a nice life with DCs and nice house etc and in recent years the ILs have reinvented themselves as doting parents and grandparents who love us all soooo much and want to be involved etc. It's a bit of a headfuck with gaslighting/ rewriting history etc as they now proclaim that having children is the best thing they ever did etc etc.
They are, however, still very negative about life in general/ how awful life has been for them etc etc even though their difficulties have all been a result of their own choices. We hate seeing them but I smile and nod and support my DH as I know that it is his decision about the extent to which we see them and I don't have a right to influence that.
DH copes with it all by keeping them at arm's length: we see them every now and then but it's very much small talk and they are not a close family.
My DS (11) is about to get his first mobile phone and I know they will want the number. I know that at some point he will have to be able to make his own decisions about his relationship with the ILs and I have to accept that, but 11 seems very young for this! I am worried that they will be constantly messaging him and a) getting to him with their negativity and b) building a relationship with him which they will then pull away from as he becomes a teenager and not babyish and cute any more, like they did with their own children. I don't want him to be dumped as my DH was.
All my DHs siblings have decided not to have children despite being happily married and have openly said that this is because their own childhood was so difficult. As such there is a lot of pressure on us and our DC to provide the perfect grandchild experience the ILs now want. There is also no precedent for the type of relationship they expect.
If anyone has had a similar situation: how do you protect your DCs whilst also accepting that you can't be in control of the relationships they have as they grow older?
Thank you!!
