I, too, am learning. 3 weeks is a great beginning...keep at it and stay strong. As for me, it has been almost 3 months that I have gone "no contact" with my addicted brother. I feel lighter, happier, more focused on my own children and husband, and I can sleep now. In the back of my mind, I worry about him, sure. I hope and pray he is ok and that he will find recovery. But it is SUCH A RELIEF to not be involved in the drama, the chaos, the BS. It feels great. You will find so much freedom in letting go. So, so much freedom. Congratulations! You should commend yourself and reward yourself.
I too owe my own progress to the people on this board and their support.
