Never resort to revenge!!!
It messes lots of stuff up
If your plan becomes a success, you are hurting your ex, making her go into negative places in her mind, maybe one being getting back at you for what you did, and ladies can be smart and come up with worst things than your plan. Also, your sending out a message that you are a asshole to other women who have heard or viewed the announcement. Thats not going to help. Plus your consquence you thought of should scare you. You don't know how your parents are going to punish you.
What you should do is follow Alex's blog about moving on from an ex, the latest blog he has up, the one with the amazing examples. Or other blogs about Exs OR read other stories on here. It should really help.
Revenge is sweet, but it can turn sour.
