A woman who is close to her mother will gravitate towards her mother, her relationship with her partner does not necessarily ime totally exclude include his family. Mothers of sons IME are pushed out in a large number of families.
I have 2 'DIL's and 1 'SIL' (they aren't married but I consider them family) I have tried very hard to avoid the pitfalls of being a MIL.
particularly after reading threads on here
Eldest sons ex is mother of his 2 children. She didn't meet me before having eldest DGC but we welcomed her, tried to make her feel at home with us. They had only been together for a few weeks months before she decided she wanted DC. Cracks in the relationship started to appear very quickly.
My DS has 'issues' that have been there since late teens. If she had got to know him and his family she would have found this out. He has, and had when they met, no stable job, no permanent roof over his head, no money saved, is emotionally volatile. It became MY fault and I should deal with him and MAKE him deal with his problems...he is mid twenties she is thirties!
We have given him support/info but ultimately he is an adult and has to seek 'help' himself.
She then chose to have a second child by him knowing he has problems.
and it is STILL my fault he is the man he is
We have offered support, practical and emotional but we, me in particular, still get the blame. She refuses to accept any responsibility for her own situation.
She sees her mother daily we see them once every few months, only when the situation is good between them. or Xmas/birthdays
My other DCs partners have no problem with me, we have a good, open good natured relationship.
I know I am trying very hard to keep lines of communication open and avoid commenting or judging but being verbally abused because of her poor choices gets very wearing. She only rings/texts when DS and her are arguing.
We adore our DGC but we are definitely not viewed as important in their lives as their maternal side by 'DIL'.
They are well cared for and she is a good mother to them, I have never and would never criticise her parenting. I would love see more of them though.
I often wonder how she will feel in twenty years time if this happens to her when DGC are grown up.
