The way he treated his pregnant/one day postpartum fiancé was legit terrifying. I remember crying for Olga when he threatened to take her barely NEWBORN baby away to the states without her. You have shitty-but-entertaining people like Angela and Ed, and then you have people like him who are pure evil and hard to watch. I think the producers even saw it, and never put them on any of the HEA or Pillow Talk type of shows.
Your friend should go for it. He shouldn’t waste any women’s time who made the mistake of thinking they were dating cause he wanted to get to know her as a person and not just have sex with her.
