MLC will take as long as it takes the person experiencing it to get through their issues, resolve them and accept the fact that they were not to blame for the lack of love, admiration and/or validation in their early years.
What do you do in the meantime? Focus on you, make a like of items that you've put off for a long time and start doing them, go to a gym, learn something new, but any of these things have to be because you want to do them for yourself, not for her. Dbing is about learning how to cope and learning how to use the skills, not to just to try to win the wayward spouse back, but can be used in your day-to-day life as well.
Follow her lead and whatever else you do...keep your expectations at zero at all times. Your wife has taken a trip to Wonderland and is trying to find herself in the looking glass. Give her as much space and time as you can. She needs to work through her issues on her own and unfortunately, you can't help her because you didn't break her.
God has given both of you the gift of time to heal. Take this time to reconnect w/your inner self as well. Take the focus off of her and what she's doing and turn it back on to you.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
