The controversial star of 'The Real Housewives of New Jersey' tells PEOPLE that none of her co-stars have offered their sympathy or support, but admits that's she's fine with it.

"They weren't my friends before the show, they weren't friends with me on the show, and they won't be friends with me when the show has come and gone. I don't expect them to reach out to me. I would actually be shocked. I would prefer not to have people be fake around me," she says.

Merrill died of a stroke on March 21.
