Search Results: sleeping with my best friend

If your husband, wife, girlfriend, or boyfriend ever accused you of: cheating with their best friend, having feelings for their best friend, or accused you of flirting with their best friend, and it was NOT true. How would you react? How would you feel?
STORY TIME:
Names: accuser=Jeff, partner=Amy, best friend= Eric (and for the purpose of this story, another friend=Erika) (others were there but were not involved)
Everyone is at a house hanging out, drinking, smoking and playing games, just having a great time. When it is Eric’s turn Amy taps him on the knee to get his attention, (because Eric NEVER pays attention and you have to YELL at him when it’s his turn.) Jeff sees this and gets angry but keeps it to himself. A bit later Amy and Erika go against each other on a game. Erika beats Amy at this game. On into the night Amy becomes annoyed with Eric taking forever and several others not paying attention. Erika sends Amy a text saying she is sorry, because Erika thinks Amy is annoyed that she beat her. Amy reads the text, smiles and says Erika I love you, in a friendly, silly kind of way because of why Erika sent the text. Jeff hears this and assumes that Amy said I love you to annoying Eric, which was not true. Again he seems angry but keeps it to himself. After everyone leaves for the night Jeff starts yelling at Amy and accusing her of telling Eric that she loved him and confronted her about her touching his knee. Amy denied saying it but Jeff didn’t believe her and kept yelling. The next morning Jeff is still angry and continues the accusation. To which Amy still denies. Amy screenshots the text from Erika and explains why and to whom she said I love you too. Jeff had no words and leaves. Jeff comes back later and apologizes and tries giving Amy a kiss and she denies him. And now Jeff is upset and sleeping on the couch. (As I last heard) who has the right to be upset? Jeff or Amy? How would you handle it? Don’t be cruel, looking for advice to give.
