Just caught up with your sitch, Brad, and I have a theory about your WAW .... immigration does strange things to some people. It's like the army ... it either breaks you or makes you stronger. Could it be, that now she is out of the sitch in Africa, and sees a whole different world, that it's gone to her head? I have heard of a few going somewhat wacko here. Could also be early MLC ... does happen, and might have been kickstarted with the move. Now, I am making huge assumptions, and do so with very little evidence, except you mentioned Zimbabwe and South Africa, and I am from the latter, and went through the whole stressful thing.
Anyway, if I am right, then you will understand when I say 'vasbyt'. You seem to be doing all the right things ... just hang in there, and try and protect yourself financially, and emotionally, and make sure you get some fun time for yourself too, even if only to go for a coffee alone or with a friend. Also, make sure your boys understand that none of this is their fault in any way.
Take care.
