Q: Given a real-life anecdote of a complex ethical situation, generate a suitable title that describes the main event/root cause of the situation. Imagine that the given text is a social media post, and you have to write the title of the post, so the users can decide to read the main text or not.
Long story short, mi bf gave me his fb password because “he trusted me with anything” I shouldn’t have accepted it, nor should I have entered the account. I checked his conversation with his bestfriend and I found out he was talking shit about me, my parents, my friends and was pretty much a different person when talking to him. AITA to have confronted him about it? He broke up with me because I “invaded his privacy”. Which I did. But I feel like it was all just because he didn’t want to deal with the repercussion of his words. 

Sorry for the bad english.

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
