The super short answer is... You're kidding yourself! Not only that but you are cheating yourself out of a healthy relationship with a healthy woman and it's not her!!!
Stick around. Read the Stickies. LEARN!!! This is not a, What can I do for her? deal. It's a, What can I do for myself?!!! kinda deal!!! I can tell you that life is not peaches and cream when married to an alcoholic. It will get worse. The question is... Do you wanna stick around and see what alcohell can bring you? It's your choice... I'm sure she'll make arrangements for your first class ticket to hell. Sounds like she's already got your suitcase packed.
ALL ABOARD THE CRAZY TRAAAAAAIN!
