Just keep working towards being friends with your husband. During the times you are together, try to make them positive (so he holds onto good thoughts and memories). As long as he's open to invitations go ahead and invite him, but do so without expectations. Also, don't push too much, just stay positive when he can't make it, smile and say, "maybe next time...."
Try to do fun things together. If you do start 'dating' again, make sure you set up some "date nights" and don't stop those even if you reconcile. I've learned that it's very important for married couples to date each other sometimes.
There is no arriving, ever. It is all a continual becoming.
