Just popping in.....I need to say something. When people find out you are separated, many people (if not most) will tell you that you should move on. Except for your closest DB friends here, people who got a divorce will say to "divorce"...almost always.
Just remember what YOU want and what God wants. Never stray from that. Do what you think you need to do to make that happen.
And, don't do anything a married man shouldn't do right now. Don't do anything you wouldn't do if you were still living with your wife right now.
