This may be its own thread, but as I look back on my relationship with my A, I wonder how many lies were told because he simply didn't remember the truth? And being faced with evidence...still couldn't remember the truth so easily defensive about it?
I had an interesting experience with him a few months back. Being on anti-depressants at the moment, my memory sucks. It is a side effect, even at the mildest dosage. I said something in a voicemail to him...forgot I even said it (and honestly still have no memory of this voicemail) I denied saying that, he pulled up his Google voice email and forwarded it to me, and then right after sent me the archived voicemail in an audio file.
It was humiliating and demeaning. Now if I catch him in a lie or a half truth, I no longer correct him. That's between him and his God. But I don't trust him.
