I hear you, OP.
The main thing keeping me awake at night is imagining my child on custody weekends and holidays with Dad. Without me there to do my little dance around to hide, minimise & make up for Dad’s behaviour. I can’t see my way through that thought yet, but I’m further along than you.
I’ve really read up on this stage of the separation journey that you and I seem to be on. I’ve talked to loads of women who’ve weathered it and come through the other side. I’ve come to some realisations (though I’m not all the way yet, by any means). I’m hoping they’ll sink into my brain and heart over time, and that seems to be true.
-the current situation (staying, playing his game) is more detrimental on the kid(s) than I realise or want to admit;
-the kid(s) actually need one happy, mature, stable parent going forward. Only one. That will have to be me, it certainly won’t be DH. And at the moment there are no adults that fit the description;
-I am more ground down than I realise by the effect of DH on me personally (I am the ‘boiled frog’ in the popular analogy) so I just can’t see the bright life beyond, the life with unexpected joys and wins. I must be focussing on the negatives/ catastrophising because that’s what boiled frogs do. Just cos I can’t see forward, doesn’t mean it isn’t there waiting for me. People I trust insist on this bit.
-I need to trust far more in the randomness of the future. Maybe DH dies in 3 weeks from an undetected condition, or a bus. Maybe he runs away with someone, leaving all the kid raising solely to me. Maybe I meet and fall in love with a crack lawyer who banishes DH to the nether realms for me (legally, I mean!). Maybe my kid is believed by a court/the law changes/I get lucky, and custody ends up not so shared. Maybe 1000 other things. I can act now, on current info, but I can’t really predict the ‘nightmare visions’ that come to me in the night.
-you can’t be prepared enough/do enough digging/have enough of a support team. Get in touch with all the experts, line up all your ducks. I picture it as a row of ‘movie dynamite detonator plunger thingos’. While I’m feeling stuck and paralysed in the relationship, I can still line up more of those damn thingos every week, quietly. Which ones I push, when, and in which order is up to me. It’s quite empowering! Knowledge really is power.
Don’t know if any of that helps. But really opening yourself to even the extreme responses on MN is usually a good exercise, in my view. What seems impossible to read and contemplate today, can be a really useful roadmap tomorrow. I’ve found that to be true, for sure.
Good luck to you. Oh, and start humming around the house. Anything, all the time. Get a singalong going with the kids. Start wearing headphones, and interacting verbally with great music and podcasts when you are able. These ‘silent treatment’ assholes hate it!
