OT: Friendships. What do you think?

It was obvious to me right off this wasn't really about your kid getting invited to the movies and it made more sense when you started talking about your ex and court.  That is stuff that is beyond stressful and it will definitely cloud your thinking and make you do things that seem unreasonable to other people.  However, if they could see inside you, they would see you have a whole lotta poop on your plate and you are dealing the best you know how.  Your friend didn't invite your son to the movie.  That's all.  She's not a bad friend.  You're not a bad person either, no matter what your ex says and no matter what happens in court.  Hang in there.  You will get through this.
