Sometimes there is no love at all. Just liking.
In this case, I know Sandy doesn't love Suraj - why should she and for that reason why would he? they are both strangers and just getting to know one another. Being married to someone does not automatically mean you are in love, far from it.
The only difference is their mentality (thinking). Suraj is the traditional/typical guy. The thinking is once you are married, you fall in love and off course desire plays a part in it as well. He, as a man, fancies Sandy, she is nice to look at and has a great figure and living in cllose quarters he see's her in all her guises...when she comes out of the bath, when dressing and etc. So he is halfway in love with her already - BUT he doesn't know her. And he really needs to get to know her.
Sandy, thinks with her head. She is never for the traditional nor dreams about her prince charming. So when she got married, it never even occurred to her to look at suraj as in 'this is my husband, ooh wouldn't it be nice to let him touch me? play with my bangles? hair? smile at each other while going about our work' and all the million other things newly wed do to spend time and get to know one another. She was depressed over her parents death, then being forcibly married and having to put aside her dreams. She doesn't even know how to connect with a man let alone this complete stranger-husband. So she treats him like that, slowly she saw that he was nice, helped her out and even defended her when needed. She became slightly warmer to him - BUT she never shown him what's in her heart because at the end of the day she is still getting to know him.
Though I think Suraj might be just a little bit in love with her but I dispute that in light of his current behaviour.
When you love someone, you never hurt them no matter how hurt you got unless its a matter of survival. For him, its not survival more about his precious mother's honour (what would the neighbours think when Sandy leaves him, his own shattered dreams of what a marriage should be like (with no basis in reality)). So for him to be nasty to her especially when he knows his horror of a mother is at fault, knows the pain sandy goes through each day trying to balance society's expectation with what she really WANTS, he can then turn around be the same as his nasty mother. This is unforgivable. I would rather he stopped speaking to her or kept his distance without the hurtful words and accusations. But then the saying 'the apple does not fall far from the tree' is especially true here - he is his mother's son!! I would in fact caution Sandy to not fall in love with him, Suraj does not handle disappointment well. That is a bitter pill to swallow, seems like his so called love comes with conditions attached. Has he conveniently forgotten his precious mother was going to throw her out within 15 days? - would he have been like this with his mother? NO!! but the moment he saw that piece of paper his colour changed. For heavens sake, with a mother like his does he honestly think he will ever get to keep a girl for one day let alone the months sandy has been there? open your eyes suraj and give thanks she has stayed put for so long!
So now, my conclusion is its not love on either one's part. For that I am really happy CVs have been true to life. I hate it when they show the bride immediately loving and being dutiful to the husband no matter what their relationshp was like before the wedding. I once watched a show where the heroine's sister got married to the villain (he forcibly put the sindoor on her) and then she was like 'he is my husband, I cannot let you hurt him' to her sister and the hero even though the villain had killed her father and was now trying to destroy heroine's married life. I swtiched off right there and then.
