My sis-in-law (bro's wife) had a boyfriend before getting married to my brother ( My bro is chump and a Cuck) . She also had a fwb .

Now the thing is my sis-in-law's father is very rich .

Now before marriage she used to spend all the money when she had a bf . Like if she and her bf went to a vacation all tickets of plane and hotels were booked by her.

Sometimes her bf even used to ask money from her for his personal expenses like for example he has to go somewhere he would ask her to book the ticket and all and she would do it. God knows how much money he used to ask from her or if she payed even for all his personal expenses.( or if he asks even now) .

Her fwb also used to ask her money .

And her bf was not exeptionally handsome or anything like that . He was just an asshole with a psychopathich face and character.

And my sis-in-law is in general extremely cruel and cunning woman .( She is cheating on my brother even after marriage) She will not give even 1 cent to you for free.

She bargains very cruelly when she goes to shopping.

So, my question is how the fuck her bf exploited her monetarilly when she is very cruel and cunning towards everyone else ( including me)

Anyone has experinece , please tell me.
