i'm sure there's some marriage that was saved by counseling, none that I know. I know several divorces where counseling was involved.
funny story, can't remember if i've shared it here
one morning before a friend's wedding, all the groomsmen are sitting at a table having breakfast. the groom asks us, most of us being friends for 30 years, to tell him the hard truth, what does he need to know, prepare him for the rest of his life. few give some simple b.s. I say pick your battles and know that when you win you lose. my best friend chimes in on how true it is. another friend, speaks up and says it should be the opposite. says how your partner should be the one you communicate with the most and you should feel able to be most honest with. after several minutes of platitudes, i ask him, aren't you and your wife both phd councilors? he says yes with clarification on whatever their degrees and studies are in. so i turn back to the groom and say, if you and your wife have about a decade each of training in how to communicate, then do so. otherwise, pick your battles and know when you win you lose.
i've never heard of a councilor or shrink that wasn't also seeing someone
