Marnie and Mark

4 of 5
The never-ending stress from their mounting debt is taking a toll on Marnie and Mark's relationship. "I blame Marnie for the debt I'm in," Mark says. "I've been angry enough that I've broken the back door slamming [it]."

Money problems have affected their sex life. "When you're all anxious and tense you don't want someone to touch you. I think we've both kind of withdrawn a lot."

"Having money problems isn't sexy at all," Mark agrees.

Ironically, the financial trouble that has put the Widlunds' marriage in crisis has also prevented them from separating. "On a couple different occasions [arguments over money have] almost ended our marriage," Marnie says. "Fortunately, neither one of us could afford to move out."
