I find it awful that my brother who is also my best friend has a fuck buddy and never told me. The only reason why I feel that I should know is because his wife is my best friend. I understand that she does not treat him the best, but that is no reason to be unfaithful. He could have at least broke up with her first. If she ever finds out it will be bad news for everybody. She has never been that type of person who can control themselves in stressful situations. She always has a huge fit and does a lot of things that she regrets after. Even though she loves me, I’m sure she will put the blame on me and assume that I knew it was going on the whole time. So for right now I am going to cross my fingers that he leaves her or that she does not find out what is really going on.
