Hi andyv: I admire your "go-getter" spirit. Keep doing the 180. Do not pursue, or you'll push her farther away. Love her by loving yourself first. For now, get involved in hobbies or activites that release tension. Or, hang-out with friends, and volunteer somewhere. Give her space to sort things out. Remember, she is still your wife. The papers have not been signed. There is time. If she speaks to you, be evasive but loving. If you see a difference in her, keep doing what you've been doing. Do not be the 24/7 man if she is still hooked on another guy. She must miss you to realize how great you are. Fight the good fight of faith!
