Forgot to add this earlier...
Why do I use the word 'accept'? It is not my word for what has happened. It is the word that plays in Suman's mind. Remember that she is an orphan.
She considers herself a burden for everybody. Including her family and Shravan.
Shravan is marrying her but he does not appear to want to. When Shravan does not actually want to marry but is majboor to do so for the sake of his family, if he spends money on his wedding, it means that spending happened on account of Suman. That is her thinking! So when he spends on his own wedding it is because of her. It is unwanted for him but he has to.
I won't debate if this thinking is true or false or even appropriate. But this is what Suman feels. That she does not want to make him spend any money. She feels it is her wedding and her 'burden'ship is just transferred from one place to another. So she does not want anybody else to spend money in this process.
When Shravan says nobody wants her, it means he does not want her either, right?
So she does not want to make a person who does not want her to spend something due to her!
Although she is optimistic about the wedding and is determined to make it work, she knows the marriage itself holds no value to Shravan or his family. She feels she is being a burden of expenses here. That is the reason I use the word 'accept'. If he spends on the wedding, in her mind it means she is 'accepting' it.
Suman does not think like us. That it is Shravan's wedding too and he has every right to spend money on it. According to her he considers her a burden. All that is at play here are her abandonment issues. Her deep seeded issues have raised their ugly head. Make sense to you? That is why I say she is a slave to her circumstances. For her the only way to be free is to not make others spend on account of her. She wants to have as low as a footprint on others as possible.
If Shravan makes her feel he is actually happy to spend on her she will be comfortable with the whole process.
Hence the word 'accept' to denote Suman's state of mind.
