Re: sincere advice
If people ‘say’ about her then it’s because what she did is wrong. Now she needs to bear the consequences.
There is no excuse for her actions and no one is going to say to her, shabash tumnai acha kaam kiya hai. She will be looked down upon and if she hasn’t the guts to deal with it, she should have considered all of this before she had an affair (and an affair need not be physical or sexual) - infidelity is not honoring your commitment to your spouse.
