I agree with all that Sree, coolie_no._1 and Kruti have said.. š
Ajai Sinha did the same thing with Manas (divorcee) and Ria (unwed mom who had had an affair with a married man who had cheated her when she was 19 or so) - both of them getting intimate within a couple of months..So out of character with Manas until then..In fact he was so conservative that when he heard Ria was an unwed mom, he was shattered and did not talk to her for a day and went and sat in a beach depressed. It was Simran who convinced him not to behave that way and go and talk to Ria and be pleasant and normal and why he should be so upset, etc..(of course she did not know that Manas had got attracted towards Ria by then). And then he changes colours within a few days?? But with Simran-Abhi and Sia-Sid, he showed no such scenes. I agree some people are more vulnerable but by picking Manas and Saakshi, it appears like he is labeling divorcees..
