Can I send this to an ex crush who has a girlfriend?

The only reason why I hurt your feelings was because I was desperate to get your attention. Back then I thought that was the only thing thatll get you to talk to me. Approach me or something... I didn't care how I'd do it and that's where I fucked up at.

I had THE biggest crush on you then. And all I wanted to do was talk and obviously wasn't mature enough. I really hurt you & all i want to do is apologize and say I'm sorry for being an inconsiderate asshole bitch.
