I've decided to ask the girl of my dreams to marry me.  I'm sure she will say yes.
That's great! Congratulations! That's exciting, and I'm sure if you're confident she will, then she will!
I do feel confident about it.  We haven't met in person yet, but she is coming to visit me in Nigeria tom
Oh, okay. Well, that is a bit different, but good luck!
Thank you.
