90 Day Fiancé is a show about love, but also insecurities such as hatred, guilt, obsession, and jealousy. Over the years, many cast members have shocked fans with their lack of trust in their partners. One example is Natalie Mordovtseva, who had always doubted her Washington native husband, Mike Youngquist. When the 38-year-old Ukrainian woman debuted on the show, she was insecure about her partner and accused him of infidelity. She left him after marriage to find other men and pursue her goals. Eventually, Natalie realized she was wrong when Mike helped her mother get to the United States and supported her despite their breakup.
