Tonight I'm going to my first Al-Anon meeting.

Here’s what I say: GET HELP FOR YOURSELF

One thing I learned a long time ago: If you don’t take care of yourself you can’t take care of anyone else.

This thread is already full of suggestions. Pick one or several or all. The important thing is to get some help for yourself.

I am sorry to hear that. It sucks.

The problem is that your mom loves her addiction more than she loves sobriety. Until that changes her life going forward is going to be much like the past. I’m sorry that your mom has this problem. Or disease. Whatever you call it, it sucks.

Sometimes, a marriage isn’t worth saving.

Seems like your dad needs some help, too. Maybe you can suggest he get some for himself? Would he care to go with you to Al-Anon? But regardless of whether or not your dad wants to go with you, YOU go and get some help for yourself.

Here’s some validation: YOU DID THE RIGHT THING. Yes, coming between grandma and the grandkids sucks. You know what sucks more? Kids having to deal with this adult shit before they’re adults. Grandma has an illness, grandma has a problem, that’s why we’re not seeing grandma this Thanksgiving - something like that, right? Best of all, it’s the truth. You chose the lesser of the two evils. That’s what responsible adults do for their kids.

“Grandma is sick, grandma has a problem. That’s why we’re not seeing grandma for Thanksgiving this year.” Adjust as appropriate for you children’s ages.

All true. And it sucks. but BRAVO to you for recognizing you need help and seeking it. Keep trying to find an Al-Anon meeting. Do an on-line meeting. Talk to a volunteer. Get some sort of counseling for yourself to help you deal with it, take care of yourself, and yes, communicate with your family.

Maybe not so much accept but deal with it and get on with your life. It’s OK to love your mother but to hate and loathe her addiction at the same time.

Yes. It sucks. How are you going to live your life and achieve success and happiness (however you define it) despite the suck?

You’re welcome. Rant away. I haven’t got anything more than validating your feelings and urging you to get help, but since it’s what I have that’s what I give you. Good luck.

What’s a “runner” in this context?

AlAnon worked wonders for a friend. Surely it’s worth a try, and best of luck with your struggle.

Update:

I spoke with my father at length yesterday. My mom admitted herself to an inpatient rehab center the day before Thanksgiving. Apparently my dad drove her (it’s about an hour and a half away from where they live), which was something she initially didn’t want: she said she felt he wanted nothing to do with her, wasn’t speaking to her, and certainly wasn’t going to take her to the rehab center. Dad basically told her that no, he did want to drive her and give her support.

He also told that he believes the impetus for her deciding to enter treatment was the fact that he had asked for a divorce. He found online some “do it yourself” divorce papers and filled them out then asked for her signature—which she gave. He said he didn’t sign them and has no plans on filing them if she gets better. In his words, “I don’t want a divorce, I want my wife back.”

I did find an updated list of meeting locations via the phone number nearwildheaven provided. I haven’t been to any yet due to the Thanksgiving holiday but there is one listed this coming Tuesday which is on my calendar to attend. I spoke with someone who had attended an “outlaw” al-anon meeting that was sponsored by a local drug rehab outpatient clinic and the national al-anon org. He warned me of something that had never occurred to me: he said that, in his experience, local al-anon meetings aren’t male-friendly. He said that many al-anon meetings are attended by women who are there because their current or past SO drank. They see it as a safe space for them and thus men are often given a frosty welcome. I have no idea if this is true or, if it is, this was a one-off event. I’m not going to let it deter me from attending one but it’s a possibility I need to be aware of.

So at this point mom’s in rehab, and I’m sure thoroughly miserable. My parent’s relationship clearly needs a lot of help, but I’m not sure either one will admit it or try to get it. I’ll do my best to support them but otherwise stand back and let them work out for themselves what’s best for them.

Part of me feels like this is “giving up” on my part. I’m a bit OCD and I want to do what I can to fix this. The objective part of my brain knows that I have no control whatsoever over their relationship and whatever healthy / unhealthy aspects are extant therein. That doesn’t help much, as the other half feels that if I could just say the right thing, make the necessary point, get them to see reason where currently they refuse or are unable to do so then all would be better.

Sigh. One soldiers on.

Apply that desire to fix things to fix the issues this brings up in yourself. Far easier said than done. But you may find it’s a productive way to channel that energy.
I’d say you’re Dad’s comment is the best news in a long time. Whether Mom will take advantage of Dad’s offer to keep trying is a different question. But absent Dad’s offer, their future and all your feelings about it would be taking a very much less-good turn about now.
Good luck. Seriously.
