As Mach1 told me so many times, just live in the moment and enjoy it to it's fullest.
I spent an awful lot of time worried about who W was talking to, what she was planning, when she'd make a decision, how we'd move forward, etc etc. Once I started really focusing on each day individually, it became so much easier to enjoy things.
After a few months of "limbo" my W told me how she wasn't ready to make a decision, how she was unhappy because of it, and how she felt guilty for keeping me in this situation. My response was something like "if this is how we're going to live during indecision, I'm happy to take this for the next 30-40 years."
