LQ, I fear for your happiness.
You say, " my wife is very fragile emotionally..." Let me rhetorically ask (in other words, don't answer this) if her condition is REALLY so delicate and has been confirmed by psychiatrists and/or neurologists to be the result of some organic deficiency OR if this "fragility" is simply a role she plays to manipulate you. If she appears to be an oh-so-delicate-shrinking-violet then YOU will have to do things for her and not complain, for she has become your burden to bear.
If she does have some real organic deficiencies, you have my sympathy but I still wonder if coddling her is going to make her stronger.
Some asshole elder will pronounce you a "spiritual threat" and you will be wondering what the hell just happened.
I hope for your sake you are well and strong; you may soon be tested.
