Welcome to SR. I hope you find comfort here.
It is tough being married to someone who is addicted. It's very frustrating being the only bread winner while a spouse is not only not contributing to the household income but draining the income with their addiction (and the behaviors that accompany it).
I hope you stick around. Learn as much as you can. And take care of you. It's very easy to allow an addict to drain our physical, emotional and psychological energy. That's why it's so very important to concentrate on self care.
