this really sounds like full blown depression. and believe me i can relate being with a spouse you love but that wont do anything to help themselves (ie - take meds)
in her own little world - she has a certain perception, a certain way that she can comfortably deal with life. but because she is not in "reality" mode, anything that counteracts HER reality is a definite attack to her well being. she goes into SURVIVAL mode.
i know it's a very tiresome job we all have here being the only ones wanting to work on these troubled r's - but - (you knew one was coming right) in the long run, if we can hold on long enough things have a way of working out
there is another piecer on here, jeannine, you need to read a couple of her last threads, her husband was WAY off the deep end, with threats and the like, scared her half to death - but when you look at how things are turning out, it's simply amazing
if there is one thing i have seen in alot of these sitches, there is an epiphany of sorts for the wayward spouse, it happens all of a sudden - it may not be on our timetable but it does happen - and when it finally DOES happen, things change in minutes instead of months
keep the faith - if this marriage is really what you want (you have kids so i know that is a consideration) then patience is the key
