I've hit a wall.. Now what?

Is this typical temper tantrum crap for a WAS?

No... that's typical of the person who was left by the WAS. Somehow you've officially reversed roles. I would tell him to get IC or some kind of help on his own and you'll consider MC after things are going better to see if reconciling is possible. Notice those words mean iffy unsure statements that still give hope. It's really surprising how your sitch turned around lately.
