How do you get over being in love with your friend?

(This is a long one sry) I met this woman over the summer, we have a ton of things in common. The biggest thing we share is a love for running, we did a bunch of races together this year and have plans for a bunch more in 2020. After a while I fell hard for her, but I don’t think she feels the same way, which is fine. I figured I’d get over it eventually, and I thought I was past it. Fast forward to today: it’s her birthday, met up with her and a few of her other friends for bday drinks at the hotel bar she works at. Later in the evening one of the other guys said he needed to use the bathroom, she offers to show him where it was. 15–20 min go by they don’t come back, I figured maybe they were having a quicky and that didn’t really bother me, but then I had to use the bathroom. The men’s room was empty when I got there (thankfully), but as I came out the two of them were coming out of the unisex bathroom and she was adjusting her outfit. I literally felt like someone gutted me with a know when I saw them, which I was definitely not expecting. I did my best to cover it up. I told them it was late and I should head home, early work blah blah, but really I just couldn’t stand the thought of spending another hour or two hiding that gutted sensation.

Long story, but how to you get over being in love (or what feels like love) with a friend? She hasn’t shown any interest in anything beyond the friendship and running we do together. Which is fine. Friends are hard to come by, and friends who run are even more rare. Is it literally a all things pass with time thing? Should I take some time for just me and avoid runs with her until the feeling passes?
