Lets be honest here.No, he wont treat them the same, Its obvious by what he said that this gc is the one he considers 'his own family' just the same as he favoured his own dd when she married.And same way the first ACTUAL gc only got a moses basket..If half this money that gets spent on his own daughter/gc is yours- if i were you id withdraw my own half NOW and stop adding to that kitty and have my own bank account for my savings.only contribute to that shared account enough for half your housekeepings/bills etc..then id treat my own dd/gc's how i wanted/when i wanted.Tbh, why are you even married still to this mean, selfish, stingy man? ?As for them just walking in, keep the door locked in future, and tell them all off for it in no uncertain terms.If it was me, id tell them also theyre lucky i didnt report them for it.!
