i think you have done a great job.. just try to be calm for few days. if you didn't do any mistakes now be as inelastic. you have your self respect right? i think he is ruining your life .. he is suspecting you in every moments right??? is it is yes sure you did correct one. no one could bring him up. he should be admitted under psychological treatment.. it is extreme way of expressing love if he didn't get his love back from his lover.. try to be calm dear... don't give him any chance sure he won't change his attitude..
