Snowkitten, with me the moment when I went from "wait-and-see paralysis" to "make some changes" came from a single realisation: That I had lost pretty much everything.
I had been clinging to the hope that if we just got over this "bad patch", one day we'd work out a way of having a good relationship. But that was a false hope. The reality was that the relationship I was in that day was a hollow, abusive sham. I'd lost any real hope of a good relationship.
I'd also been clinging to the thought that I didn't want to break up our children's home. But the reality was that our children's home was already broken. My children were confused, fearful and sad. I'd lost the fantasy that my children were better off with both mum and dad together.
I'd also been hanging on to the thought that I could take it, I could deal with the abuse and the drama and the tension, and could cope with it all and keep a lid on everything and I'd be ok. I wasn't. The reality was that the stress was making me physically ill. I lost the fantasy that I could cope with anything.
That moment when I realised that I'd lost everything what I held most dear - my relationship, my children's best interests, my own health - was both terrifying and liberating. Terrifying because the utter fucking shambles that my life had become was suddenly obvious. And liberating because it meant that I no longer had to worry about making changes and my own actions making things worse. Pretty much anything I could do would make things better because it couldn't get much worse than what I was already living through. And so I ended the relationship. And life got immeasurably better. Not overnight, but there was finally a light at the end of the tunnel.
I wish I could show you the difference in my own health and happiness, and the extraordinary difference in my children since my alcoholic ex and I split up. My children had withdrawn into shells I didn't even see because all my attention was on trying to manage the alcoholic chaos and drama. Now, though, they're well out of those shells and are funny, happy, lovely and able to just be kids.
I'd urge you to read The Bridge. The whole Classic Threads bit of the friends and family section of Sober Recovery is well worth a look, too, although it will take you a while to wade through it all.
