It depends on your tone of voice, tbh.
If you are asking AIBU?, then of course, I understand perfectly where you're coming from: the hardest heart and most contrary nature could never accuse you of BU. You should also leave the bastard.
If, however, you meant AIBU, well! Of course you are BU. I'm amazed you had to ask! Don't you realise there are other important, life changing events taking place in the World today???
