Am I right to be annoyed or overreacting?

If you are that uncomfortable, then don't hang out with her when she is with her BF. Only when it is just you and her. What does your BF think of there behavior? Maybe he could talk to him, man to man.There is nothing wrong with open displays of affection. My hubby and I still "show" affection for each other. Just not acting like we need to get a room.
