"So being that you have this knowledge what do you think is my best course of action?"
....first things first....if I were you I'd get off the booze....that means total abstinence; 24 hours at a time...you may or may not get your wife back; that outcome is uncertain...but I'll tell you what is certain...if you go back to hitting the bottle your life will get worse; MUCH worse in fact.
....I drank and ran around on my first wife; those two behaviors go hand in hand....after 9 years she rightfully dumped me over it and I don't blame her one bit...I told her later she did me a favor because it made me get off the booze...and after I was off the sauce and the fog started to lift; I was glad to be divorced from her...you might feel the same about your run-around wife after you get off the booze too....I've been clean and sober for 34 years and have seen that happen a lot.
....if you don't get help and try to quit on your own; you'll probably go back to drinking....go to AA...it's free and it works. Good luck!
