Kind of fell for the wrong person... :/

There’s this boy, and I really like him. He’s so nice and just genuinely a lovely person.

But well... he has a girlfriend. And I feel horrible that I have a major crush on him because I know I really shouldn’t. Really, really shouldn’t. I would never do anything about it as I honestly don’t think I could even consider it.

I honestly don’t even know what to do about it. I’ve tried to just stop liking him, but I wish it were that easy. Honestly I do.

Any advice? At all.
