Living with Addisons and a lying husband

Frustrating is a good work on how I feel.
Living with Addison's has not been the easiest thing, usually tired then went into a depression. I use to have tons of energy and never was sad... Things sure change.
My husband which I blame for all my stress in my life is trying to be a helpful husband right now, it won't last.
He only wants to help  me know because I caught him on sites on his phone when he went to Vancouver for a night, googling men erotic massages and more. He told me he never did anything, he always says that. One night away from his wife and he is out searching. Wow.
So now he is helping with dishes etc.... Funny!!! Doing dishes is going to FIX the problem!
I feel when you put pain on someone and you feel bad that you hurt them and you love them that you would stop hurting them. But it doesn't happen in the real world, I just get kicked on more when I am down.
Some days, I feel like why bother going on. It is so painful and hurtful.
