Backstory for anyone who cares to read:
My friend has been "dating" a guy in prison for 3 years. Up until 3 months ago she was also sleeping with dudes while she was in this relationship. Now that the guy is out she caught him with another girl and flipped out. I personally don't think she should be surprised because she has been sleeping with other guys during this "relationship" so why is it wrong for him to see another girl? If she wanted monogamy when he got out she should've been specific about that instead of sleeping around (and telling him about it btw) and just expecting him to be ok with it.
So what would you do if you were in this situation? I know what you're thinking, "I wouldn't be in this situation, Mishelle, I love myself," but try to suspend your disbelief for 5 mins.
