Broken
I don’t know – any more than anyone else here – if she’s having a physical affair with this man or not.
What I stopped at was your comments about her relapses in drinking. I think there is a very high probability that THAT is where the issues are.
I have some experience in dealing with alcoholics and alcoholic families.
I doubt many illnesses are as misunderstood as alcoholism. It’s this weird reverse-allergy, where you are attracted to the substance that creates these mixed metabolic and psychological signals in you. It’s not the classic uncle who pisses himself at the family-party, nor the bum sleeping in a box on the sidewalk. The alcoholic can be your kids teacher, your boss, your brother or sister, the person that only drinks 1-2 a year, but each time ends up passed out in a ditch. The term "functional" alcoholic is basically a bomb with a timer. It’s a disease that if untreated has a near 100% fatality-rate – if from organ failure, falling down stairs or wrapping your car around a street-sign.
When she is drinking there is NOTHING that she prioritizes above her ability to drink. Her focus is on the next drink – not the next family dinner, not the next morning at work, not the next ANYTHING. It’s the next drink.
Of course people have various levels of accountability... Like a parent might be aware that they have to pick up little Joe at daycare at five, and they might try to stop the binge that started with that one drink at lunch so they are reasonably "sober" when they set off. Still... their need for drink will make them drive Joe while legally not capable of doing so...( I sometimes mention this example, because as a cop I guess I arrested close to a dozen parents for DUI with their kids in the car).
As-is your wife has a drinking companion in OM. I think that’s his main role. The snoring comment – that could be as "innocent" as him having passed out while on a binge. Or not... but honestly to me that is not the issue.
I am 100% certain that while she is drinking there is NO WAY you two can reconcile.
The only way that could happen – while she was still drinking – is if you provided a better path to her ongoing drinking than hanging out with fellow drunk and enabler. Like if he ran out of funds, or decided on sobriety and started AA... she would be back to you like metal filling to a magnet.
Seventeen years.... There is a whole international organization for families and others impacted by alcholics called Al Anon... Chances are your whole relationship with her is affected by her drinking. I strongly encourage you to look into Al Anon irrespective of what she does.
Your GF?
You can’t make her stop drinking. What you can do is refuse to be an enabler. What you can do is recognize that no matter what – whether she was 100% faithful sexually to you or went out and turned tricks with the whole local football team – her priority in life would be the NEXT DRINK.
What you can do is refuse to enable THAT.
Since you can’t force her to quit then all you can do is offer enforceable ultimatums allowing her to choose what path she wants. With luck – she will choose sobriety. But friend – with luck she won’t...
I say the later because within 2 years of ending this – chances are you will be fine.
The former – sobriety – is a long, long path. But can also be rewarding because she isn’t defined by her drinking. She can "return" as the true "her".
I would tell her that you aren’t happy that she’s spending so much time with OM and you see this as not being faithful to your relationship. However – you also realize this is important for her to continue her drinking. The drinking is the clincher – while she drinks, she isn’t the person you want because she’s being controlled by her drinking. If she wasn’t drinking she wouldn’t find a need to be around OM.
Tell her that you are moving on. There isn’t any rush. It takes time to detangle your lives, but you are not enabling her drinking any more, nor will you wait for her inevitable sinking deeper into drinking and eventual death from alcoholism.
If she wants the relationship she needs to decide to commit to sobriety. That might control your pace out of this relationship. Simply not drinking won’t do it for you, but if she were to start AA, appear sober, start a program with a sponsor and show you her 10 day badge, 50 day badge and 100 day badge... then and only then you might get some belief that sobriety might last this time.
Be aware that alcoholism isn’t treatable per se. It’s only manageable. That management is through sobriety, and to maintain sobriety people regularly go somewhere that holds them accountable. Like AA. If she manages her sobriety now, she will be going to daily meetings for probably the next 100 days, then 2-3 per week for a year or two, then 1 per week, then maybe every other week... This is ongoing, lifetime treatment.
Finally – Over the years on this site I think I have seen a pattern with many dealing with addicts. That’s where the addict/alcoholic will maintain a semi-affair in order to divert the marital issues from the addiction to the infidelity. Expect her to offer to stop drinking with him if you allow her to drink at home. Just keep in mind that is not going to last.
