i’m a recovering alcoholic (6 years sober next week, weather permitting).
i destroyed my life through my drinking. i knew i was hurting people but honestly? i didn’t care. it was all about me, and my pain, and my self-pity.
there were a lot of rock bottoms on the way to the last one. each of them terrible, and frightening, and dangerous. i thought i was invincible. i very nearly died. i lost everything, and i mean everything. i was as rock-bottom as it gets and i am lucky and grateful to have survived it.
i finally got sober with AA. a little while into recovery, i met a man through online dating. i knew he liked a drink. i thought it was fine, that as long as I was sober, all would be well. i fell in love and moved in with him, all in the knowledge that he was at best an incipient alcoholic. i think in my grandiose early sobriety i thought i could save him.
OP, you cannot save an alcoholic. they can only do it for themselves. i stayed with my ex for 5 years, all the time things deteriorating, knowing i had completely fucked up. in the process of trying to save him, i let others down and am still living with the fallout from that.
i finally left him 8 months ago. his race to the bottom is accelerating. i miss him - i loved him very much. but the man i fell in love with disappeared a long, long time ago. he lives in chaos now, and i don’t doubt it will kill him in the end, because he just doesn’t want to stop.
please take it from someone who has lived both sides of this - you must not involve your children in this doomed relationship. and it is doomed, has been since the start, because you don’t know who he is, not really.
value yourself, protect your children, and stop this, now. i guarantee that you will live to regret it if not.
