Sounds like your kinda of restuck a bit, that's ok, sometimes when that happens its time to back away, and sometimes they need to feel you chasing them a bit. The hard part is knowing which one to do. Its important that you let her make that first move thou.
She'll tell you, maybe not using exact words, what she wants. If you get a "so what have you been up to?" then proceed carefully. If you don't hear from her, or get an "I've been busy", validate and keep dim I think. Crap who knows. Its all such a fine fine line.
Its so important, yet so hard, to not think about it until the situation presents itself. Its important I think, that you keep yourself as busy as possible. You really haven't had a time that detachment was an option. Which makes it all hit home everytime theres contact, even a simple text. Don't get down thou, just realize its all a process that's going to take time, a long time.
Do what you feel is right for you. You are the one that has to live with the results, and only you know your wife. Hang in there buddy, you've got my full support and hope that things work out. Don't be afraid to give it some time if that what you think you need to do. The choices are yours of course. You'll know by her actions/responses how to proceed. Listening is still your best ally.
