Need some advice. Without giving too much info, I am a locally competitive male in my late 20's. I live in a pretty large town with a dedicated running scene, owing to its amazing running trails and parks. Over the last year, I have developed a very close relationship with a female runner close to my age. She is my first new female friend in several years. We became training partners because of our interests and running performance. She is pretty fast, so we do easy runs, long runs, and occasional track work together.
Here is the catch, I am engaged. My fiancee has been extremely supportive. She occasionally runs, but really likes that I have someone I can run with seriously. My fiancee and my training partner have met and are friendly. My training partner is also in a long-term committed relationship. I don't want to cheat on my fiancee or be a home-wrecker. I just feel a strong infatuation toward my training partner. We spend a lot of time together and often text back and forth for hours.
So LR braintrust, give me some advice. I have a crush on my training partner, what should I do? Is it just speed goggles? Do we need to stop being training partners? Will the crush fade? Do I just need to get too fast to run with her? Are pics required?
