勇気 (Yuuki)'s Favorite

Hi there friends. I have been aromantic for all of my life, but have recently developed a crush. I have asked said person to their face if they like me, and they've never replied. But as two asexuals, we've done everything from holding hands to sleeping together in the same bed. It has been a few months since I confessed, and it weighs heavily on my self esteem that I might just simply not be attractive. Personality wise. Physically. I'm starting to think I what I'm doing to myself by liking someone is an experience gone sour. Can anyone share any red flags for when it is time to give up on a crush? Keep in mind, I'm asexual, so anything involving sex isn't necessary. Thanks! (づ￣ ³￣)づ
