Hey guys - looking for some advice for my next move here:

Me:
Hey Melissa - thanks for helping me win a bet with my buddy.

Her:
What bet?

Me: Wait a minute, this is between my friend and I. If you want in, you're gonna have to earn our trust.

Her:
so then you emailing me telling me you made a bet about me was only a ploy to get me to earn your trust?

Thoughts on my next line here?
