Been there babe, madisgram is right. If he can't see the beauty in the chaos then he ain't right for you. Doesn't solve your housing situation though. Not sure about that one.

He should love your mensa self and stop going on about it being your fault. Maybe you could kindly point out that by being with him, he contributes to your wellbeing and consider himself lucky that he does not suffer the same terrors as you. It takes two to tango.

I hope you get it sorted for your sake. You are far too precious to put up with crap and you should be loved for ALL your stuff......not just the predictable, reliable stuff.
