I've been the woman on the other side of this a few times. I work in a male-dominated industry and have lost almost every person who I thought was a close friend to this exact situation. It's been devastating to find again and again that people who I thought were my actual real friends, people I hung out with all the time, only valued me as a potential hookup. I feel completely disposable. It sucks. So just keep in mind that is how she's gonna feel if you do a big emotional confession and then block her forever.

How to get over a crush? A crush is mostly a fantasy. Right now your fantasy only has one target, but you can redirect your thoughts to a new target. You just need that new target. Start dating other women who you can build fantasies about. Start forming those new emotional connections. Start texting, start chatting, and I guarantee that the minute you have found just one new woman who you find yourself connecting with on a romantic level, your current "crush" feelings for your friend will be pushed way to the back burner.
