Long story; So short version I left highly abusive exH because he turned his aggression on to our two young DC (biologically his). I left last Nov.
His family are fully aware of what he did (I didn't tell them but am 100% certain that they know the full story).
DD had a birthday last week - not one member of his family (except my ex-mil) sent a birthday card. I really thought ex's paternal nan, aunt and brother (the nice ones in the family) would still bother with the DC. AIBU to think that is really shitty of them to not even send DD a birthday card?
