No, T. I don't think so. IMO, it's more a sign that things weren't done "right" when you let him back in the house. It moved too quickly, and he wasn't ready for the heavy-lifting that piecing requires. (I do think there might be some unresolved issues with how you two communicate specifically about finances and needs, but I think we've covered that in spades and that's what your professional MC is for.)
I didn't do it right in 2006. My crap came back to haunt me in 2014.
Try to look at this as an opportunity to get it right. Though I know that's impossible right now ...
