Another one bites the dust.

Married at First Sight star Tracey Jewel has called it quits with Sean Thomsen just weeks after Nine's top-rating television show wrapped up.

The 35-year-old author and marketing consultant told New Idea magazine she broke up with her on-screen boyfriend last week because their relationship had become "quite strained".

"Because he's FIFO [fly-in, fly-out] he's not always here and with that lifestyle there's no stability," she said. "My core needs in a relationship are commitment, stability and security and Sean can't give that to me. That's why I can't move to Melbourne with him.

"I need my friends and my support [network] around me. I'm not ready to move. It's a miracle me and Sean have made it this far, to be honest."
