Like DON is saying, I think it's not meant for "marriage" as such, but more that she would love Abhi for the rest of her life, no point in marrying someone else.
Anyways, I didn't like that she shared this with him, this way. It somewhere calls for sympathy..Not something I would say in her situation. I would have just said, I will take my life as it comes, you do the same.
Abhi asks for her sympathy all the time.
