Sorry, I got caught up in other stuff.
We can get so involved in problems with family members.
Lots of what I was going to say has already been said.
Through the years I have found that whilst I may not agree with what they do, the choices they make with people in their lives that it is their choice. They may be blind as a bat but the more we do to try and make them see that, the more they will attach themselves to prove us wrong and our continued well meaning "interference" can also prolong it. We need to step back and hope, let them make their own mistakes and to be there to help pick up the pieces when needed.
