Dunno. He misunderstood (catastrophically) a text I sent him, went into Radio Silence, very cross, and I didn't even know why he was upset.
i do now. I kind of see his point, I would have been wounded too if I thought I saw what he thought he saw me send him.
I went to end it, I didn't want to, but I told him that Radio Silence is NOT on.
He called me, we talked some more, I told him not to do that to me again and that I would not panic.
We'll see. he's tried to make it up to me.
this is a very new relationship, we are only weeks into this and the max I get to see him is 2x a week. There is no soul searching so far, no deep and meaningfuls, it is just enjoying each other's company and spending time together. I love that, I NEED that.
I have a feeling that we now need to talk more and chat less. IYCWIM 
I'm reluctant to go too deep and searching, I'm enjoying the nice, I talk myself to death at therapy, I'm kinda bored with listening to myself go on about my stuff, the last place I want to drag that carcass of grief is into his life/space etc.
I have told him a few things about my 'past' but only stuff that is pertinent. I don't want to appear damaged, but by the same token I need to get across that I am sensitive in some areas, and not the all vanquishing person I may give the impression of being.
