Each and every time DH and I have a disagreement he tells my MIL. If it's a serious disagreement it will be a full-on phonecall, where I can hear him mentioning me.
DH does come from a country with different family dynamics where relationships with family are closer (and I suppose they share more) but I am absolutely fed up of it and feel like I'm in a primary school being reported to the teacher.
It is at the stage where I now don't engage with MIL as she knows just about every flaw I have and every issue I have had with my DH.
I am absolutely fed up with it now.
