How do you know what's the truth? 
I mean I suppose it is theoretically possible to be that un self-aware.
I am mulling over a long-gone relationship now, so don't "need" to do anything. I only realised some time after the (v difficult) breakup that he was verbally, emotionally, and occasionally physically abusive, and I've suppressed a lot of memories (eg it was only after I came across some old emails of mine to a friend that I remembered he probably cheated, more than once).
It seems to happen often on here - cheaters accuse their partners of cheating, controlling people accuse their parners of controlling. I suppose the EA is so intangible I'm finding it harder to remember that I didn't abuse him, whereas I can be quite certain I didn't cheat although I was often accused of it. But what if I really was/am EA and I drove him to the rest of it?
