There's a lot worse things out there than what you described. I've seen some pretty "crazy" behavior. The title of your post made me smile.
Anyway. I know it's tough to tell about the deep stuff. but in the first meeting, just stay surface level. Get to know the relationship first before jumping into it head-on. Do you know what I mean? Would you dive head first into a frozen pool? Although some do, but that's not the point. The main thing is to get started.
I hope this helps. and also realize something that I realized today. From a book, "The Miracle Equation", "You. Are. Limitless."
