Well, the only suggestion that I have to offer you is to take this opportunity to practice being compassionate. Firstly with yourself, and then with him.
Or to expand your capacity to love... first, love yourself, and then others.
or practice something wonderful and exciting and that you enjoy being regardless of what he is doing or not doing.
What are YOU doing?
This is where the focus can keep you centered and balanced, keep the focus off of him and his shortcomings, and step into being the bigger you that you are when fear is not presenting itself!
Much love and light to you!
