Oh how sweet. You know how to play garba? Do you get all dressed up in chaniya choli as well 
Anyway here most people are commenting on the fact that he is using her. How about she is using him. Oh yeah women do use men.
I think this girl is scared and still emotionally too attached to let go. Although she has accepted to move on it will be very difficult to do so. It could work out well for her because she may be able to get over him once she immediately gets married. In which case she has been smart and used him well. Or she will always compare her husband to him and wonder..“what if…”. In which case she has ruined her own life as well as her husband’s.
If it were me, I would break it off now…a situation could arise where he gets married first and then he is the one to break it off. How devastating is that?
