Hi anam--I am so sorry you were treated so badly by that man. I can see he hurt you very deeply. You are so wise to not want to get back together with him. It seems you still have a lot of anger about the situation so yes it would be a good idea to seek some therapy so that you can process any pent up emotions. I am not sure what you mean by dual personality but that sounds like a condition that could be looked into in therapy also. I hope one day you will be able to find some peace. All the best to you.

ps--I know this site is huge and very overwhelming with its many forums and subforums. fyi, if you post in the main Depression forum you will probably get a lot more feedback.
