happynewyear, this is all ringing bells now - dh used to be like that too - stamp his feet and yell, like the two 3.5 year olds we now have! So yes walking out for me did work - I drove to his mums after he had left for work - I rang him from a layby just before the motorway said i'd had enough, i couldn't live like it anymore and needed time to clear my head and give him chance to think. He couldn't shout back as he was at work, so just said, fine. Later though he went nuts, effing and blinding, swore he had diswoned his mum because she 'took my side' which she didn't she was just looking out for her grandkids.
Anyway, i stayed from thursday til sunday, sometimes talking nicely and feeling like we had made headway then he would go out with his mates and get nailed and ring me at 2am calling me all sorts.
I went back on the sunday, quite apprehensive (it had never been my intension to leave forever, was just some time out), and he welcomed me with opened arms, we talked and talked like we never talked before....he made all sorts of promises (which I took with a pinch of salt initially as i was still sore), which 2 years later he has still kept. We get up on alternate mornings with the kids at weekends, as they are early risers and we both work full time....he has a lads holiday, usually ski-ing and i have a girly holiday, usually sun sea and sand in portugal. We do family stuff together and when the rugby season starts again in september, we will all be polling up to watch daddy play (weather permitting)......when he says i'm off out to so and so...i don't grump and ask why, or say no, you not going because i know if I say the same to him then he is fine with that too.
PLEASE PLEASE try to talk to him once more, maybe write everything down - how he makes you feel, how it is damaging your relationship and potentially you as a family. It's so worth it if you can come out the other side.
