After the death of 90 Day Fiancé star Elizabeth Castravet's father, Chuck Potthast, it was clear the reality TV star was leaning on her family for love and support. "Two weeks ago, tragedy struck our family and it has left us completely shattered. My sweet, loving, and caring dad went to heaven. We're trying to figure out how to navigate our lives and move forward without him," Elizabeth wrote via Instagram on November 23, announcing her father's death in a joint post with her husband, Andrei Castravet.
