I usually hate most TIFU posts but I’m really sorry

You’ll move on, and you’ll look back fondly on your time with him.

I had a similar love story although I’m gay, and so I never ended up confessing but I’m sure it would’ve played out similarly.

How long has it been since you messaged him? Maybe he’s processing it still? I don’t expect him to reciprocate but maybe he’ll accept it and still be friends with you.

Knowing he doesn’t feel the same way, you can at least get a sense of closure. You had an idealistic version of him in your mind, and hopefully you can move past it now.
