yupz u sed it right--maan has ego prob--he has maintained an image fer himself, in his eyes and in front of every1 else that he hates women, "pyaar jaisay waheyat emotions kay liyay meray pass time nahi hai" and soo onn stuff.. so thatz y he doesnt wana admit!
geet on the other hand has lost the slightest of faith she had in love after dev deceived her! and now that shez preggy she doesnt evn wana think of loving sum1--cuz she thinks that obviously no1 will accept a preggy woman! or she wants to live life on her own terms and earn enouf to bring up her child properly---she doesnt wana shift her attention elsewhere.
i think dev never loved her..cuz wen u love sum1 u dont make their life a living hell!!
hez a playboy! har larki perh line marta hai!! and wen he saw geet he waz crazily attracted to her beauty and innocence and then wen he got a chance to spend a night wid another gurl--so he tuk full advantage of it!
hez findin geet cuz hez scared that the truth might cum out! he thinks that churailtara doesnt noe he slept wid her! and if geet blurts out the truth, then the night spendin thing will be out as well!
maan and dadi will definitely kill him and kick him outa the house and he wont get any share of the property--
plus he might also think that geet wud take help of the police to take revenge--
so hez jus darpok and is worried abt the after-affects which might occur once the truth is in front of every1!!
