Feeling lost

I appreciate that it doesn't work for everyone, but would it be worth giving relationship counselling a try?

I agree hold off and let the dust settle.

If the split is meant to be, then announce it
However if you have some space and then decide you do love each other after all, some friends/family will struggle to accept the relationship moving forward (especially the ones that announced "well I never liked him/her anyway" or the ones that picked sides etc)

I'm with Gonegirl here. It doesn't sound as though you're meant to be apart, especially as you say that your husband " would come back ".
Have a good long talk and air your differences then you may fully decide which way you're going. Don't do anything in haste !

What Gonegirl says. Re-consider.

That exclamation mark was meant to be a comma

But if he was your best friend! and you are obviously feeling down and unmotivated, why do it? Why not try again?

You don't sound at all sure that you want to separate.

I am single, not through choice. He decided he did not love me any more. The first few months are the worst. You will learn to live by yourself and enjoy the time-freedom. You can do what you want, when you want. I draw the line there. I chose to spend the rest of my life on my own. Good luck with whatever you decide to do

Don’t be afraid. You must have had good reasons.

Move forward with hope and confidence
