Udham's behaviour

Guys I have recently started watching this show what I am unable to understand is that why is Udham so rude with Nellam its obvious that he doesn't love her but is there some other reason behind his behaviour I mean could be he was forced to marry her or he may be having another woman in his life Any idea guys?

Even i suspect him of having another women in his life :-\

ya chances of other woman are there and it is previously said that uddham do not wanted to get married till 2 years but he had too, so may be he is still annoyed.

Someone needs to tell him what Buddha said;

it is a true statement Visha, one I wish I could learn myself how to do .. letting go of my anger that is

I think its mainly cuz he didn't want to get married and becuz he had to do what mummy ji said he had to get marry to neelam, but he really needs to stop taking out his anger on his innocent wife Neelam
