As above. Have been there (in a slightly different way), I remember the wedding ring thing. It was horrible at the time, a very dark place that I thought I'd never get out of, but a few years on I have never been happier. It does get better.
3 pieces of advice:
- Don't move out;
- Stop smoking and drinking. Completely. You yourself need to deal with this, not through a prop. I stopped drinking totally for 2 months and it is partly what saved me, I think. It messes you up, particularly sleep patterns. Don't just have "one", focus your anger on maintaining that self-discipline;
- Stay away from other women until you feel ready to move on. Otherwise it gets worse when that inevitably goes wrong as you're not over this one.
