It is kind of like having sex when/where you could be caught. It heightens the excitement.
I believe that both of you got so bogged down in everyday burdens of "life" that it took all the fun out of things between you. It all becomes about work, kids, material things, and little time for intimacy. If the only time you have for each other is after the kids are in bed and both of you are exhausted from the activities that day.....chances are that not many "new" activities are going to be added to the menu that night. Things get stale and dull and that is why a lot of spouse opt to walk away. They was excitement in their lives. Only you know if that describes your case or not, but something sure seem to turn her on when she saw you. Just the thought that you were "suppose" to be hands-off since the two of your were separated might have been exciting for her. It just works like that for some people. Whatever they consider to be "taboo", excites them.
Talk to you later, Sandi
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
