You are doing the very same thing you are accusing him of doing.
1) For opening up a thread to bash him (whoever he is). That's not taking the high road.
2) You are calling him childish, immature, overgrown baby, not a real man, etc. That's hardly classy! Matter of fact, it's hating 2.0.
If you have truly moved on (I don't know how if you are married already unless the person you are talking about is your husband) and you are at peace with yourself and are not bitter, opening up a thread to bash him flies in the face of it.
No need to give him the oxygen of publicity. Just take the high road, the higher moral ground, and move on quietly. The more you bash him the more likely he'll appear in your dreams and I doubt you'd want that at this point. Am I wrong?
