How do I get over someone?

I was kinda seeing this guy for a year, but we never made anything official, which looking back, I probably should’ve cut things off or stayed just friends. I was stupid and thought things would change. I felt like they would because of everything we talked about and what I went through with him. I just haven’t had that strong of feelings for someone before. I’ve gone on dates with other guys before him, but I never got really intimate with any of them. This guy was my first, which is why I think it feels so hard to get over him.

Anyways, things ended in January. It just didn’t work out as expected, but I keep thinking about him almost every day, and it’s driving me crazy. I just want to get past this and move on. I keep thinking about everything that happened, and I keep wondering if he’s doing okay now. I’ve even had dreams of him and keep going through all the memories. It’s just a never-ending cycle, and it makes me sad every time I do think about him. I just keep thinking, how can I worry and still care about someone who hurt me so bad?

I just want to know how to get over him.

Does anyone have any advice?

I’ll try anything I just need some direction to move on.
