MARRIED At First Sight star Mark broke down in tears at the end of tonight's episode of the E4 show.
The teaser for tomorrow's instalment sees the customer service manager get very emotional during a serious conversation with his husband Sean.
Mark tied the knot with Sean as part of this year's series of the social experiment on E4.
Sean felt an initial attraction to Mark, however the feelings weren't reciprocated.
Despite that, the pair got close during their honeymoon and seemed to be going from strength to strength.

However this week they've had a few bumps in the road as Sean hasn't been feeling it like he once was.
In a clip with Mark and Sean looking very serious, the show voice over says: "And with his marriage hanging in the balance..."
Sean says to Mark: "I don't want to hurt you."
The voice over continues: "Sean must make a potentially devastating decision."
Sean adds: "I need to be true to myself in this one."
Mark then breaks down in tears.
Fans think this could be the end for the two.
One wrote on X: "Wait… Sean & Mark’s marriage is in turmoil."
Another said: "So that's making it look like, Sean and Mark are done."
"Mark just constantly being hurt is painful to watch," a third added.
