How do I (20M) stop feeling upset about my best friend (20F) hooking up with random Tinder guys when I have feelings for her?

A few years ago, I met a girl who would later become my best friend. She had a boyfriend at the time that she was very serious with, and I wasn't attracted to her at first up until a few months ago. When we started to become very close to each other, she would always show me physical affection, such as cuddling and resting her head on my shoulder, which is probably what led me to develop feelings for her, looking back. We even shared a bed together on a few occasions, but nothing happened because she was in a long-distance relationship.

She is single now, but for some reason she seems very hesitant to show any physical affection like she did before and I now love her very deeply, but I know I can't tell her how I feel because she would always tell me stories about how she never had any guy friends in school because they always ended up liking her. I also know that she doesn't feel the same way about me because she has hinted multiple times how she finds me unattractive and thinks that we have "different outlooks on life" to have a lasting future together.

These past few months, since she's been single, she has gone to Tinder just to hook up quite frequently, and she's asked me to help set up her account and always tells me about guys she's been messaging and it really upsets me. I want her to be happy, but I also don't want to feel this way inside anymore. I also don't want her to see me as one of those other guys that she had to stop being friends with because they had feelings for her, so I can't tell her how I really feel about her. I really value our friendship, but even if we never become anything more, how do I stop feeling bad about her ditching plans with me to hook up with random guys she meets on Tinder?

TL;DR: I have really strong feelings for my best friend that I can't tell her about without feeling like I'm betraying her, and can't help but feel bad when she hooks up with random guys on Tinder almost every weekend.
