Joe Giudice's speculated affair might cost him his wife, Teresa's, loyalty as their fraud trial gets closer, Radar Online reported Saturday.

An insider told the site, "After all that other news hit, there's got to be doubt in her mind. Every time she turns around, she's away, she's seeing pictures of him somewhere else. So I have a feeling that she's starting to say, 'Are you kidding me?' Like 'Stand by my man but meanwhile every time I go somewhere, he's doing something else?'"

The source added that Teresa went as far as scolding her friend for sticking with her husband, who was sent to prison.

"[Teresa] said, 'You waited for him?' And she goes, 'Oh, you're a better person than me.'"

This new stance Teresa has taken is much different from her loyal attitude in the past.

The insider said, "She would never talk like that...She was a stand by your man type of situation."

They continued to say that Teresa has put other things into perspective and set herself and her and Joe's children as more of a priority than worrying about him.

"I think she's finally starting to realize it: 'I better cover my own [butt]. I have four kids to take care of.'"

This report comes just days after a separate source claimed that Joe was only with Teresa because he sees her as his "meal ticket."

That source claimed, "She's supporting him. Could you imagine supporting some bastard who is running around spending your money on somebody else? Awful. I don't get it."

The couple is set to start trial for 41 fraud charges this April. If convicted, they could get up to 50 years in prison.
