Your to be brother in law cheated a married woman and you think he is going to be faithful to your sister. WoW, all the best!
I think she can go to small claims tribuinal or through the grey areas
The solution is simple: tell your sister to dump the guy and let him solve his own problems.
No, seriously. Would you want your sister to marry a guy who borrowed money from and dated a married woman?
And actually, as nasty as the married woman is, she's right about one thing: your sister should stop seeing that fella.
maybe u all don't know about the sister leh? maybe she dated someone's married husband..
