Um, considering how many desi guys go around sleeping around before marriage and don't get any heat for it? Likewise, I don't see any reason she should get heat for it, unless society is willing to change their ways and start berating men for doing the same crap.

Its not about sleeping around, its about bringing a baby in this world just for the selfish reason, that is, because she WANTED one. Bringing a baby without having an established, secure home team is the stupidest thing a person can do. She should be publicly lashed.
