I have been using the validation approach that I've learned about here - and also restating my moral code (conversationally) rather than in boundary form (as he has not crossed the line lately)... .is it fair to think that this is having some effect - or am I just being naive?
Thanks for your thoughts.
Hey Aussieguy!
I think it's fair to think this is having
some effect. Validation works wonders

The truer we are to ourselves, living up to our own moral code, the more others learn to trust us. When we're aware of our own boundaries and trust ourselves to enforce them, we come across as more confident.
Perhaps your friend is started to get a better idea of what you're made of

Just a few of my thoughts... .
