Shellie Zimmerman says she never really knew the man she was married to for 6 years -- but one thing she knows for sure ... he's selfish to the core.
George Zimmerman's soon-to-be ex-wife appeared on "Good Morning America" Friday and made it clear there's no love lost.
Shellie has filed for divorce. She wants the 2 dogs and a cut of any judgment George gets in his defamation lawsuit against NBC.
As TMZ first reported, she's getting more than $4k a month from the Zimmerman Legal Defense Fund.
