Kate Gosselin says she is having a hard time relying on anyone these days.

"[I trust] a very, very small group of people," the reality star, 34, says in an interview airing Monday night on TLC.

Since her 10-year marriage to husband Jon has deteriorated, she complains that many people she once considered close have sold her out to the press.

"When you look around, and very close trusted people who would never cash you in, for lack of better words, and those people do that and people leave your house and tell completely different stories, you tend not to trust people," she says.

In the interview, Gosselin also says their eight kids have become more introverted since she and Jon told them they were divorcing.

Speaking at a New York City synagogue Sunday night, Jon apologized for any harm he may have caused his family.

"I want to apologize to Kate in private for having public relationships, because if she had done that to me, I would have been pissed," he said. "Looking back on it, it seems like a knife in the back."
