Run-down but up on running

After a few weeks of laziness, I returned to running yesterday. I had gone on a bus ride to Minneapolis/St.Paul and found that my fitness had slipped. So back to running. It feels good and contrary to logic, I eat less when I run.
On the flip side, I am trying to deal with the realization that a woman I had met over a year ago and had been communicating with since (and who I thought was the woman of my dreams) is not interested in sharing her life with me. Hard part is that I cannot fathom the reason why. I expect this is another of life's interesting twists.
