I read once that recovering from this, especially from our sitches (lbs), is like always taking 2 steps forward and 1 step back. And that you are doing this climbing a mountain. I guess the idea was that it was this painful climb to the summit, the worst of it, and then down the other side things start getting easier, after 1- to - several years. Hard, right?
But even more so is that when you engage with the old relationship (i.e. attempt reconciliation, etc), but it wasn't time to work out, then you go back partway down the mountain, to where you were a few weeks or months previously, and have to start the 2 steps forward and one back from that place again.
I hope that makes sense. I guess what I'm trying to say is that it's totally normal what you're feeling, even though it's hard. Sometimes I take refuge in the idea that my feelings ARE normal, because the rest of what's happening is not. I am normal, it's good to feel this way, because that is how people are supposed to feel and act!
Anyways, long winded way of saying you're doing good, you're coping, it will get better, 2 steps forward tomorrow towards that summit, stay strong!
