If he wanted he would have said yes to that desi girl by now but that desi girl is his second option & he is dragging her along, until he finds the right one to ditch her.
He is wasting her time, kinda playing with her feeling & emotions too just because he is “confused”.
What I am wondering is, you guys didn’t talk about your relationship status in that 1 year? She must have asked where its going? Or you must have gave her some hints hence she is planning her wedding day with you as girls dont just start planning their weddings with every random stranger out there.
