In this exclusive clip from Sunday’s brand new ’90 Day Fiancé,’ Mike and Natalie are embroiled in yet another massive fight, and this time, Natalie insults his looks. During last week’s episode, the two went to couples therapy, and Mike bluntly told Natalie he was not in love with her anymore and wondered why they were still trying to push through with a marriage. In this exclusive clip from Sunday’s episode, the two are still arguing, and Natalie once again brings up the fact that she thinks he cheated on her with his female best friend while she was in Ukraine. Mike again insists that he did nothing wrong. ’90 Day Fiancé’ airs Sundays at 8 p.m. ET/PT on TLC.
