Reading this thread and others like it, I am contantly surprised how many of you say that one should never discuss adult children's relationships with them, and that our adult children should not dream of asking our advice!
My concept of family is very different:
while I agree that we should never interfere, or proffer unwanted advice, to me family is who you turn to first if something is worrying you, or is really going wrong.
When my son rang two years ago, almost in tears, as his partner was leaving him, he asked if he could come here, and of course we both said yes. As it turned out, they agreed to solve their differences and stayed together, without him needing to turn to us, but that was all to the good, (I hope).
But the priniciple holds - who do you turn to, if not to your families?
Professional advice may indeed be necessary or desirable, but to me it is only an uncaring, unloving family that does not share problems and worries, as well as all the good things.
