I like and Love the Girl and send the marriage
proposal through my parents to her parents.
They are agreed by the girl is not convincing

P.S. I have came to know that the girl
      loves me one year before, but never tells me
      or indicate me.

My questions are :

1) What should i do to convince her.?
2) What are the chances of my marriage with her?
3) Is she has an other affiar?
4) I  she is going to marry him?

Marriage are made in heaven. Tapping the wrong door , will not solve your problem, just like you posting in wrong forum. Do things in write way with concentration, you will a get correct solution to your problem.

With no offence meant, Please do post your query in vedic reading room, you may get a write answer to your query. Likewise approach the girl in the right way , certainly she may be able answer your call

Think positive and work on the issue you need to handle.

You yourself has decided your love is lost in first stage itself. That itself indicate that you are not serious and positive in your approach
