Welcome back ladies and gentlemen of the internet. When you're married with kids, it's easy to let things build up more and more until you can't take it anymore. Sometimes we push down so many of our everyday emotions that we don't even know how to express them in a healthy way. Healthy communication is a cornerstone of a healthy relationship; it's okay to have issues, but it's all about how they're brought up.
In this Reddit thread, the original poster (OP) is a man who is a bit fed up with his wife's behavior. She's been actively rude to him in public, bordering on abusive. The situation came to a cross when they went to their son's school play, in which she ruined the entire performance by talking over it. Not only did she talk over the play, but she became visibly hostile and louder when her husband told her to not talk over the play. Some people have anger management issues.
