’90 Day Fiance’: Nikki and Mark’s ‘Not Normal’ Relationship Prompts Awkward Family Meeting (Exclusive Video)

The happy couple spars about having kids — again

Hey, Mark and Nikki — maybe it’s time to just seek out age-appropriate partners.

The “90 Day Fiance” couple quarrel again on Sunday’s episode over whether babies are in their shared future. Mark, a 58-year-old father of four, is unequivocally done with having more children.

Perhaps he should have thought about that before proposing marriage to a 19-year-old, something his niece refers to as “not normal” in an advanced clip obtained by TheWrap.

“Even when I planned to have children, I didn’t plan to wake up alone with four children in diapers,” Mark says. “It was a major, major responsibility, and I’m thinking — that’s not the plan [now].”

Nikki isn’t totally sold on their apparent deal. She still plans to push Mark a bit down the road — but he’ll be tough to turn around.

“What I don’t want to do is spend my decades of quality time finishing off somebody else’s dream,” Mark explains. “That would make me a fool.”

You might be there already, Mark. Watch the video above.

“90 Day Fiance” airs Sunday at 10 p.m. ET on TLC.
