My partner has I think a pretty toxic relationship with his DD
She always been spoiled and used to getting her own way. When it was her wedding her GM paid for a lot of it, as well as when she went crying to her for a car saying her kids weren't safe in the one she had. She gets her own way. Now her dad's getting divorced she's getting involved in that too she knows that she blackmails my partner with the GK so he's afraid to upset her, so he's handing over the capital in their property to his stbx to keep the DD sweet.
On top of this she's always hinting that's she's having to pay for this and that, bear in mind she has a husband and good job as a dental nurse and is 37.
I know he supports her financially now and again but it's not always for necessities I think he should sort himself out first!
It's her ingratitude that bothers so much... And making him feel obligated to give up all he's worked for...
