I am still married. Separation is imminent; we have discussed it. Married over 27 years, but about half of those have been rocky. My mood swings and drinking when I was down (sober over a year, but it's too late from her perspective) pretty much did it in. We have been separated in the same house for a few years. She won't share a bed, even for short episodes. We sleep in separate rooms. Oddly enough, I think sobriety and stability (sort of) are making the idea of actually legally separating higher. She cares enough about me to feel responsible and wouldn't do it when I would crash and burn. She doesn't state it directly like that, but she says it in a round about way.
