"You break my trust" is in present tense which means that the person you are talking to always breaks your trust! The more common and natural way of saying is "You broke my trust" which means that someone just did something bad to you for which you don't trust him/her anymore. Believe me, I didn't break your trust either!!! ^_^

sentence is right, but believe me i didn't break your trust :D

In my idea " breach of trust " is more correct .
