As for detach and GAL it's definitely not easy, but as I always say anything worthwhile is NEVER easy. The hardest part for me is balancing being indifferent and not malicious. You cannot do something to be malicious or "one up" her. It will only work against you. Always stay calm and collected and always think through any decision and ask yourself "Am I doing this because it is best for me? Or am I doing this to "one up" my W?"
I have learned the hard way that snooping never works out in your favor. There are some things I did back in December that if I hadn't we probably would be farther along at a full reconcile than what we are at now. In fact I'm fairly certain of it, BUT also realize you are human and you are going to make mistakes. Do not linger on these mistakes, take the opportunity to learn from them but do not let them drag you down.
