yes it might be wrong ..
but it would be a good read....
I really think you need to prove to your self as much as we want to get back at someone it will only make matters more hurtful to you.Your anger and pain will start all over again,you are worth so much more.You will heal and you need lot of happiness so don't pour poison on him sometimes it is flamable so don't get near it.
post it ..as one of my fave sights say...writing is sooo therapeutic wussssssaaaaaaaaa
Sometimes it's not a question of right or wrong, but being smart or less so.
You can obviously do it but might regret it later on. So hold the thought and think about it. Moreover he is your ex for a reason....... just let it all go and move on with your life.
Anything put in writing is at risk to be seen by anyone.....If he is abusive and expects to get away with it he should not have put it in writing...
Years ago I was in a relationship where I was being verbally abused on a daily basis (slightly different situation, I know ), it was something I had never encountered before but I could not get him to stop,.....In the end I told him whatever you say to me in private......I am going to make public, ( I was going to tell both of our families and they knew me well enough to know I was not being a drama queen.)
He changed his behaviour after that and I seemed to have more of his respect.
