Jason Collins has a ex-fiancee who is quite surprised.
Carolyn Moos (who played a few seasons in the WNBA) dated Collins for seven years and was engaged to him until they broke up in 2009 … after Collins pulled the plug on their wedding.
Carolyn tells TMZ, she never once suspected he was gay, so the news is shocking. She says Collins eventually revealed everything last weekend — just days before his big announcement — and said that his homosexuality was the real reason he ended things with her.
At the time of their breakup, Carolyn says Jason gave a bunch of BS reasons for calling it quits … and she could never understand what went wrong, until now.
