That's a tough one. I had a hard time with this, too. It seems that being suddenly single makes you hyper aware of the couples everywhere. I even hated listening to people at work discussing their spouses and plans.
I will tell you that time helps. As you adjust to your sitch, it gets easier.
Keep doing what you're doing. Keep connecting with family and friends. Start doing those things that you were interested in and never had time for before. This time is for you to rediscover who YOU are. Continue to strive to be the best Fell you can be, and make sure you are doing it for you. In doing so you make yourself the better option.
Keep your expectations at zero. Remember this doesn't mean you can't have hope. Detaching helps tremendously. The sooner you can do this and love your W from a distance, the better you will feel.
From what you write it sounds like you've at least hit the ground jogging. There will be bumps along the way, but the more you make this journey about you the smoother the path will become. You're on the right track!
