I can understand that at times it's easy to slip up - don't beat yourself up about it too much. I think one reason why moving out will be good for your sitch is that it will change the environment, at the moment you and your H seem to be orbiting around each other, repeating the same pattern. In the long run that is no good for either of you, particularly you.
Have you thought much about why the same pattern keeps appearing, why your resolve crumbles? Is it the comfort of intimacy that makes you hope that what is happening isn't really happening? What can you do to change things? A 180 like that may get through to your H.
Sorry, have to go and get some sleep, am really tired today. I hope you have a good Christmas and a smooth move. NB I'm really missing my W today - I guess that's no surprise. My fatal mistake is looking at photos of us, she's so lovely and she was happy. My internet access will be patchy over the next few days, so take care, I'll try to drop by when I can.
Happy Christmas all,
Max
