What To Say While Proposing A Girl?

I would say...the truth. First make sure you want to be with this person forever. Remember your going to have to see them everyday for the rest of you life and deal with all their moods and pet peeves and flaws. If you feel that their attributes surpass that, then pop the question. Be sweet,honest,unique, and romantic. Remember this is one of the most important things that happen to a girl in her life.
 
good luck!

Hi there you just need to make her believe that you are the only one who can make her happy and no one else can tell answer to this question as much  accurately you can give so don;t think much just go and talk to her

If your just friends wait a while then ask her out. After 6 months or so, take her to a fancy restraunt, or for a walk in the park, say you love her and want to be with her for the rest of your life, then propose. Good luck!!!!! Xoxo

I say firstly about herself after that by seeing time propose the girl

It's not so much the perfect words that are said.
It's being truly authentic and sharing your feelings and dreams of spending your lives together.
Love is a beautiful wonderment - I hope all goes well.

Say that you love her and that you will make her happy for the rest of her life

Give her an engagement ring and say will you marry me  I want to spend my rest of d life with you
