Sorry you're feeling a bit pants today. Hormones can be a pain can't they? I used to get really angry at certain times of the month in the past, but find that taking starflower oil seems to help even things out- might be worth a try if you haven't before.
I thought it was really interesting that you mentioned your H wanting to distance right now after the positive steps he was taking last week. I think it can be hard for the WAS to consistently move towards us. I kind of expected that once my H started taking steps towards me it would be a smooth path and contact would increase progressively until a 'magic' day when we were just together again.
But from reading the success stories, I think what happens is more of a feeling their way. So every time they take a step towards us, they need a bit of time to regroup before they feel safe enough to take another. My H may be doing this (although it's early days), and I wonder if your H is too. If he's distancing right now, he might just be regrouping, rather than being content to be apart permanently.....Anyway, I'm going on a bit and probably not making sense any more!
