Give it time. The first few weeks and months are the hardest. You are raw emotionally and it is heart breaking but focus on you, do things to keep your mind off the situation. For now, your spouse wants the separation, and you do need to respect that. Does not mean that in the future things can't change.
I think, for most of us, we want to be able to live in the past and future. But all you have is this moment. For right now, the situation is what it is. Pursuing reconciliation may only push your spouse further away. So try not to do that, no R talks (either positive OR negative). Have no expectations. Just try to heal. What is going to happen will happen, but if you try to rush things, it will definitely be disastrous.
Im still standin better than I ever did looking like a true survivor feeling like a little kid Im still standin after all this time and Im picking up the pieces of my life without you on my mind..
