confused about karishma

I really can't believe that karishma is rajat's ex girlfriend seriously think about it he does'nt seem to be a person who can have an ex gf. I think she is an old acquaintance who is impressed by rajat's charm just like dev and so when rajat seeks help from her she readily agrees. he will tell anushka that she is my ex gf trying to make her jealous rajat himself will never have any kind of romantic feeling for karishma but she will fall for him seeing his personality then she will try and convince him that he loves her and not anu that time he will just tell karishma to go away but as we all know how she is she will try and finally trap rajat. I think many of you will agree with me.

I find Rajat a very charming person. He is open minded. So why can't he have friends. He studied for a long time. The worked ..he is at least 25+ . Karishma could be one of his past love interests. A man has to go through lots of relationships before he knows who suits him perfectly..and what true love is all about.
