Jim Carrey has a new girlfriend and she is a Russian student named Anastasia Vitkina. She is the ex of one of Jim Carrey's friends. In my opinion, Jim is walking on very thin ice. It is really tough to date someone who is the ex of one of your friends. The chances of the relationship working are probably much less than a friendship is worth. You always have to wonder in these situations whether your significant other liked the person they are dating now while the two of you were dating. Did they have an affair while you were dating? These are very tricky questions. Have you had this happen to you? Have you done it before? Do you still have your friend?
