Keep your head up Stacey. I'm only a couple months into this, but in a very similar situation as you.
Things that I felt, that it sounds like you are feeling
It will feel like the world is crumbling around you The OP will be the focus of your life for a while H will be changing in mood, and you will key into those Life feels like it is a whip, and you are on the tip being slung around
3 months into the spiral, and 2 months into the separation I can assure you -
While every day there are ups and down, and seeing your ex can be hard, things do get better. You will regain the ability to function, your pride, and also start to get a clear vision of your spouse and the relationship you had.
You will find strength that you never knew existed, as well as find that you have deep friendships that are valuable and lasting.
I know it's hard to go through this, but you are not alone. Keep you head up, follow Sandi's rules, Detach and GAL. You will make it through this.
