I want to tell my ex husband that he was a psycho. Should I?
Why do you want to tell him he was a psycho?
I'd like to let him know how unhappy I was in the marriage.
It's good to be honest with your ex, but wouldn't it have been better if you let him know how his behavior affected you while you were still married? At this point, it's water under the bridge.
Nah. My ex husband was a psycho and it's going to make him look bad at the office.
It's not going to make anything better and it would only cause him to be more involved in your life if you are messing with him at his office like that. Just forget about it and move on and find a better guy.
