I get it LexieCat, one Al-Anon meeting that I went too, all the wives there were still with the alcoholic, a few of them for more than 30 years. It's part of what made me realize that meeting wasn't for me, I needed to find a different one.
So if that happens OP, try a different meeting. And know that it is easier to leave a bf/gf then a spouse, from a paperwork/law standpoint at least.
