So you're upset, angry or disappointed with me.

 Then you need to tell me. And you need to tell me the real, actual, complete reason(s) why.

Not bottle it up until one day you explode at me or at some other innocent person that had nothing to do with it.

And NOT take it out on me in passive aggressive, back-door, roundabout ways, like being harder on me in some other way or blaming me for unrelated crap (stuff I didn't actually do), or becoming paranoid of me and taking it out on me, or expecting me to take the fall for everyone else's crap as "the least I can do" for you or for anyone else, or desperately seeking help for your emotions by pretending I did something else that I didn't do or had some other attitude I didn't have or that we got into a fight that never actually happened.

Like, be straightforward with me... or get out of my life until you can. And I mean totally out of my life until you can... not trying to get even in some sneaky way by some back exit by telling people exaggerated or made-up or "metaphorical" crap about me behind my back in an effort to get justice or comfort or validation without having to actually say what actually happened.

I don't bite people because they're honest with me. I MIGHT bite people because they aren't, especially if afterwards they blame me for not knowing or for other crap I didn't do, trying to level the playing field in the best way they know how, perhaps telling themselves that taking the blame for them is the least I can do for them or take the fall for. 

If you need something, including to be left alone, or need attention, you need to tell or ask me. I won't bite your head off. I'm not one of those people who will call you manipulative when you're straightforward and treat you like you're a more honest good person when you're manipulative. I know it's hell to be trapped in that cycle, and I know I need more appreciation for your predicament. For a while it was mine too. But the very fact that it's hell means we all need out of it.
