This is just another case of CAE - crazy-a$$ explanation.
WASs look for something - anything - to explain their inexplicable behavior. The better a spouse you were, the crazier the stuff they latch on to.
One 5'8 125 lb woman was told she was too overweight.
My ex told me I "walked too heavy" - and taught our DAUGHTER to walk too heavy!!! (Now, mind you, I asked all my friends and family if I had some weird gate disturbance and they all said no; but if by chance i DID walk too heavy, and my daughter did too, wouldn't you think it was GENETIC, not learned???????)
People have been told all kinds of crazy things like some completely minor incident 20 years ago.
Odds are she LIKED you being close with her family - until she started cheating and now it is a liability because her family is less likely to believe crazy lies about how this is all your fault.
