Okay, slow down keemosabe. You made a call, turns out not to have been a good call, but you made it.
Alert the media: Humans are fallible.
Lesson-learned; now you know: There's a line you can't safely cross. "It" isn't there, whatever the "it" is that was required in that situation.
I agree with the implication of your assessment "it was just a conquest because I haven't been giving him attention" -- it's that power-shift thing I'd written about a couple threads ago and am experiencing now. It has to be about Monsoor, so when it wasn't, he had to take action and turn on the Pepe LePew charm; when it was (i.e., when you were "happily" married and (wo)manning the Home Front), he didn't have to lift a finger and could focus on all the other things that had to be all about Le Shmedlap.
Okay.
So you're a Left-Behind who, in spite of everything, still digs the Wayward. Take a number, right? You know that about yourself now, and you know what it means in terms of all future interactions.
Give yourself two breaks and call someone in the morning.
