That’s really rough I had a similar situation and I know how painful it can be. Best advice I can give is to just move on the longer you mourn it and keep waiting for something to change the worse you’ll feel and at the end of the day your friend made a decision and lost out on you not the other way around
I also had a similar situation where my best friend of several years and I would get so close to dating or we would and he’d break up with me shortly into it. We even had moments of doing relationship things together but he wouldn’t put a label on it saying he didn’t want to ruin our friendship. It can be hard but you will find someone else who’s ready and willing to commit to you
