ThePainNeverDies, David is an abuser which means that EVERYTHING is about him ALL the time. Abusers are deeply damaged and insecure beings. Unable to assign value to themselves, they are enslaved to the judgments of others and are compelled to "beg" validation of their self-worth from others by constantly "proving" their superior worthiness to exist to compensate for their inner feelings of inferiority, impotency, worthlessness, incompetence, etc., that they fear will consume them should they fail to obtain said validation. So, enhancing how others perceive and assign value to them is paramount, and one of their favorite techniques is to elevate themselves by diminishing others - in your particular situation, David is attempting to elevate himself by diminishing you by portraying you to others as "less than" himself - and he especially wants you to see yourself as "less than" him, as well. He has to make you look bad - has to make it look like he was doing you a favor by being with you - has to vilify you in his own mind and in the minds of others so he can play the martyr and justify abusing you. To say that abusers do not take rejection well is an understatement. He sees your breaking it off with him and moving on with your life as an excessively cruel personal attack because by doing so you are withholding the validation of his self-worth that he so desperately needs in order to survive - you're saying that you don't need him and you can make it without him - you're saying that he's not good enough for you - blahblahblah.

Abusers will NOT be ignored!!! David is going to do everything in his power to keep your attention focused on him - to force you to expend time and energy thinking about and dealing with him, and to draw your attention and energy away from your life and current relationship - will initiate confrontations to exert control over your emotions and to justify abusing you - will cause you problems to punish you for failing to acknowledge his superiority by refusing to submit to and serve his twisted will. Best thing to do is not react/respond - don't allow him to control your emotions - don't allow him to manipulate you into engaging with him. Remember, it's all about exerting power and control over you - and the truth is that the only real power and control he has over you is that which you allow him to have, so don't give it to him or he'll suck the life right out of you.

You said, "...he started saying that if I wasn't being such a ******, he wouldn't have to come at stupid o'clock." Abusers always place the blame for their abusive behaviors on their victims; e.g., "If you were a better person, I would be able to behave and treat you better." You cannot reason with him or end things amicably or remain friends with him because he is not your friend, and he has no use for you if you are not going to submit to his will. In order to abuse someone, you first must dehumanize them - redefine their identity as nothing more than "property" and possessing no inherent value other than that assigned to it by its owner. The only value any other human being has to an abuser is determined by the extent to which that person can be used by the abuser to serve the abuser's self-interests. Period.

You have tried to get him to see things from your perspective; the problem is that, due to his damage/dysfunction that turned him into an abuser, he is incapable of empathizing with others - incapable of comprehending that concept - you might as well be an alien from another planet speaking a language he cannot understand. All he knows and all that matters is what he feels - and withholding validation of his self-worth threatens his very existence - he MUST have his "fix" of Power, Authority, Superiority, Dominance, and Control over everyone and everything within his grasp - he MUST forcibly impose his will on you and others in order to justify his existence - he must enslave others to his judgment and force them to beg validation from him just as he is enslaved to and forced to beg from others - and it will always be this way - he cannot change because he is incapable of admitting or even recognizing that he needs to change.

Of course he didn't let you know that "something was wrong" for 3 months - that's the ever-popular "set up" - a way to blind-side you - make you feel guilty - make you feel that you are to blame - make you feel that you have mistreated and victimized poor, defenseless him - blahblah - boohoohoo. Don't fall for it - it's a trick.

He cannot stand that you are becoming yourself again - how dare you define your own identity and determine your own destiny - you're HIS "property" and have no rights. HE wants to control how others perceive you and even how you perceive yourself by forcibly imposing on you a false identity that he has defined to serve his purposes - to justify mistreating you - to USE you as his target, scapegoat, and sacrificial victim just so he can feel like a big, strong, important man. This is what abusers do and they just cannot feel good about themselves unless they're shoving someone's face into the dirt.

Walk away from that living death and create the identity and life you choose for yourself. Hoping all the best for you.
