16F 17M I finally said yes, and he left hours later. Now he wants another chance.

Three years ago, one of my friends confessed that he liked me, but I never gave him an answer because I would completely freeze whenever it came to him. Over time, our friendship became toxic and we stopped talking.

A year ago, he came back and asked for another chance. I realized I might actually love him, so after thinking carefully, I finally said yes the first time I'd ever considered someone that seriously. But our relationship lasted only 5 hours before he suddenly said, "I'm out." I blocked him everywhere and moved on after a difficult few days.

Six months later, he contacted my cousin saying that someone else had access to his account that night and that he wanted to apologize for the misunderstanding. I never unblocked him.

Yesterday I saw him again, and just seeing him made me panic and leave immediately. When I looked back, he gave me a look that felt like he wanted me to hear him out.

Should I unblock him for closure, or is it better to leave everything in the past?

I'm hella confused about everything. Like I know I'm just a teenager, and I don't even want to admit or believe it, but I think I love him. Ughhh I don't know. Why do I keep looking for him in everyone else???
