Married At First Sight Australia's Tracey stayed with cheating husband 'out of spite'

Married at First Sight participant Tracey Jewel has had a rough time on the show, finding her new husband Dean Wells cheated on her early on in their marriage.

But despite the lying, cheating and Dean's horrible rapping skills, she's sticking with him - and the couple remain committed after the series ended.

Many would ask why, but Jewel explained to Three's The Project that her decision was simple.

"I decided to stay because I signed up for the experiment for a reason, and I guess I was still hanging on to the glimmer of hope of our connection that was really obvious from our wedding day," she said.

"And a little bit of spite."

Now the show is airing she's become somewhat of a counsellor to other couples, and finds herself approached in the street by other victims of infidelity.

"They go straight into sharing - they've been cheated on or they've cheated, and how the Davina and Dean saga has hit a nerve for them," she said.

"I feel like I've turned into this relationship counsellor."
