Eventually we went to stay with his brother and SIL who told us that PIL had told them we hadn't told them we were visiting
Even if and when you DO tell them explicitly when you ARE visiting, they LIE to others to make DH look shit.
MrSphinxster, They are not interested, they don't care (Sorry :( ) They care more about making you look bad than the actual truth. Making you look bad to the whole family means they can resume the martyr role. They clearly resent your happiness.
Email them ONCE to let them know, because otherwise you will feel guilty and will feel in the wrong, (because this is what they trained you to feel) but then leave it.
Sphinxster you have done and are doing an outstanding job in supporting your H in this. He is lucky to have you. Dealing with this stuff alone is awful.
I get the comments from other posters about you being in the FOG yourself, but i believe they are mistaken. It's not FOG, its hope/faith that others are like us.
Thing is, if you have not had to deal with toxics growing up, you truly still hold out for people not to be as awful as they are, it's incredible for you to contemplate that they won't just wake up one day and be normal.
Thing is, that's our version of normal vs theirs. They are being normal. That's who they are.
