Come on a girl, madly in love finds her hubby being kissed by another woman, who was loving him and may be is loving him, thinks there is distance between her and her husband but does not know the reason for a long time will obivisouly be depressed, it just that Mittal should not have given the drink to her. We know about Kripa's drinking habits, they are always used by the Writers.
What ever Kripa did was just out of insecure love. It was embarrising, she did make a fool out of herself, but there was just one point she was driving behind it, she is a rockstar does not mean she can't have her husband distnaced away from her.
This is what i think, her act is justified to an extent, may be Angad should have draged her out immediately. But Angad is always a sweet husband they way he carried out and gave a kiss while she was sleeping beautiful.
