I cannot agree that there can be any weak moment when one can stoop to the level of cheating on one's spouse...the moment is never weak..its the individuals commitment that needs to be questioned...and its not a forced physical /emotional contact that is happening..its at will of the cheating spouse and the third person..Not to be forgiven at all...
IMHO, each and every person is capable of sustaining themselves and even their kids, and if not they should ensure they make themselves capable to that extent..
Homemaking is perfectly acceptable and respectable profession, but we should always have a fall back...and not depend on the spouse so much, that you cannot make both ends meet if the marriage collapses...
In Mona's case, she should now build her identity, get her kids back and forget Pradeep the cheater...
