Mango, do you think it may be time to think about minimizing contact permanently with your spouse since he seems to be stuck in a rut of lifelong serial relapse? Like you've done with your FOO?
You seem to spend so much of your own precious life energy thinking about him and his issues.
I don't mean this critically in any way, but for years you keep letting him back in your life and he continues to fail to maintain sobriety.
When is enough enough?
