This is the biggest reason why I think she only CHOSE to forget him but the fact is that she can't forget him. Those feelings will always be there no matter what but she has a messed up habit of burying them just like she did when she thought Armaan had left her. Didn't we think she had forgotton him then too? I don't think she can ever get rid of Armaan but she has this ability to block him out and when she does that she becomes this weirdo!
