But if that happens, Rekha ji! are you ready to take the responsibility.
I am very sure if she has said it then she meant it.
Killing is not easy, but for maniac nothing is impossible. I myself had found 10-15 sharp edged shaving blades lying naked on a tripod next to my pillow once I got up inthe morning. That incident still bring shivers in my spine.
Rekha ji! you cannot compare the your mental stability with the one who has lost it, whatever be the reason. Now all the bonding forces are missing like trust, love, humour, companionship and most important bond i.e. child who has not born yet.
I would suggest it is better to part ways. Because the suspicion will haunt them for ever.
