How to proceed?

A little over a month ago my wife left me. She cited a bunch of reasons. She didn't feel we were necessarily good for one another as she thought we had both let our lives stagnate while together. She said she was no longer attracted to me. Anyhow, we didn't completely leave each others lives and continued to talk a little bit. To make a long story short, we met one day in order to finally decide if we were going to try to work things out of not after she had expressed no interest in working things out previous. She shocked me by wanting to actually try to work things out. She wanted to maintain a romantic relationship while living separately and see how it works out. Since then things have been great for the most part. As a general trend I have found every is getting better and better. She describes it as being a few steps forward and a few steps back but generally moving forward. A big part of this is because I think I am putting too much stock in the day to day, or even minute to minute for that matter. The other night we kissed, a real kiss, for the first time since she left. One that both of us seemed to be very much in to. At this point, I feel like talking about our relationship is more damaging than helpful as it makes being with me a little bit emotionally stressful, so I feel I should probably move away from that. At the same time, I am a little scared so I find it really hard not to go looking for reassurances. Sorry if this is a little rambling, but does anyone have any advice on how I should proceed?
