One of the comment is interesting:
"There are two things: either love or hate." The commentator thinks that they should have liked each other and should still love one another but, they couldn’t express it.
He speculates, "May be, both Rajesh and Karishma used to love each other. But karishma was married in a young age and there was no way Rajesh could have married her."
Whatever might be the reason, they look good in screen and the viewers love the couple in the movies. Personal lives are much different and more important.
