Falling again

Me: You better be careful, keep up all this sweet talk and I may just fall for you.
Him: You know I will be on the lookout if you fall for me. That way I can catch you.

I met someone and I'm really nervous because he says things like this. We share more interests than anyone I have ever met and can talk on the phone for hours. I'm constantly reminding myself to not clench up and run just because I have been hurt. Because this really could be it. And I can't let this opportunity pass by.
