Should I end a friendship with a man who keeps trying for more?

This is a man I have been friends with for a year. The friendship has been important to me. We’ve been through a lot together, as friends. We talk nearly every day. I care about him a lot, as a friend. He has a monster crush on me now though and what has happened is he randomly hits on me, acts jealous or starts acting like a boyfriend instead of a friend, and I have to remind him we’re just friends. He gets hurt, and I nurse his hurt feelings and try to repair the damaged friendship. We agree to be friends, then bam it happens again and again. I hate seeing him get hurt like that. And although I care deeply about him as a friend I think I need to end the friendship so as to not keep hurting him, because he seems to develop false hopes.

I honestly would date him, but there are so many things wrong and red flags. He has a lot of problems and issues. I have a lot of concerns. There’s a reason I’ve kept it just friends.
