DO NOT send any missives to your wife at this time! You want her back? The only way that you will have a fighting chance of her even thinking of returning is to let her go. Your expectations need to be lowered to zero. You have to drop the rope, practice detachment and living your life as if she isn't coming back. Many of them, when they see that you are moving on w/your life, will begin to take notice that they may lose you. Right now, you are sending her all of the messages that she needs to know that you are still out there waiting for her.
Leave her be! Give her the time and space she needs to work through her issues. If you don't, you will lost her completely and she will not even consider returning to the relationship. Drop the rope! Keep the focus on you, do things for you and yes, to keep your mind off of what she's doing. She's going to do whatever she needs to do to figure herself out. You didn't break her, therefore you can't fix her. She has to do the hard work in order to do that.
Please, please do not send anything to her. It will not help at this time.
A question for you.....I am curious....Why are you here if you are not going to listen to the people who are posting to you? You want to save your marriage? Then please start listening to the people who are posting to you. The advice that they've been providing is golden.
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.
