Good for you on all fronts! Good for crying, good for running, and good with the MC and the W seeming, for now, to be willing to push ahead. Take it one step at a time, and brace yourself for a sudden reversal. I'm not saying that will happen as I don't know your wife, and heck, your wife may not even now her wishes one moment to the next. She could be sincerely saying one thing today, but then have a totally different mood tomorrow. I hate to rain on the parade, but from what I've read, and what I've experienced myself, these type of switches come out of nowhere. They can really mess you up if you aren't at least aware that people in MLC do these things. The last meaningful face to face contact I had with my W was in October. It was a fun, flirty conversation for about 45 minutes. We didn't talk about relationship issues at all. I was encouraged. But then a few days later she refused to see me (after hinting at the earlier conversation that she might want to do so). Then, a few weeks later she began spewing venom when we unexpectedly saw each other.
That's just my story,but others have experienced similar things. Enjoy the good feelings, but just brace yourself. This ride often takes sudden and unexpected turns, for the better and the worse. That's one reason why it's so hard.
In the meantime, keep taking care of yourself. One day at a time.
