You need to step back and allow her to come to you. Only text her in an emergency. If she texts you, wait an hour or so before you reply or even longer. She needs to realize that you are busy and not sitting on that phone waiting for her call/text.

The best way to get her attention is to live your life to the fullest. Get out there and GAL. Be the man were when she met you. If you think that there are things that you need to change about yourself, now is the time to do it and do it for YOU, not your wife.

She can't miss you if you are available and texting, etc....give her lots of space and time. Be mysterious. You do not need to tell her everything you are doing. For example, if she asks you to come over, tell her that you are busy, but you could make the trip another evening.

Read the links that I posted. They will help 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.
