Break up!!!

Four years back i met him.he was pretending to be sweet and nice.i was attracted by his character and the person whom i thought he was.we started loving each other.there were obviously many ups and downs in our relationship.i thought it was not a big deal and then i moved on.i could not hold on longer when he started doubting me with my friend.he thought that i and my friend were in relationship and he concluded that without even finding out a proof.one night he ringed me up and told hell amount of bad words,blabbered many non sense.i couldnt hold on his call for long since i couldnt hear any more bad words. after 49 minutes and 33 seconds i cut his call.i left a text message for him after that.it read something like this :"lets break up!!!!you couldnt understand me in this four years,now you will never ever be able to understand me in the comming 40 years.......good bye".after that i never ever got a message or call from him.after this incident i dont trust or love anybody fully.....am i right by doing this???am i hurting a sinciere person by not doing so????
