Movieline contains a piece called “100 Factoids of Love” by LEIGH NILES.
Factoid #49 [with a small picture of SLY and JENNIFER]: SYLVESTER STALLONE broke up with his girlfriend of five years, model JENNIFER FLAVIN, by FedEx-ing her a letter in 1994, when he began dating ANGIE EVERHART; a year and a half later, he went back to FLAVIN and she married him.
