That's a bad sign, Steve. Bad, bad, bad. The first phone conversation should be small talk to just catch up and get a feel for each other. She blew her load right away. That's scary man. Play it safe. If you decide to put your dick in crazy, be ready to change your phone number and relocate.
Seriously... that's a bad sign in my eyes. Sure, you probably felt flattered, but who in the hell says that kind of shit (with tears in their eyes) after 20 years? Crazy people. Crazy people say that kind of shit.
Tread carefully.
