Is what I wrote wrong?

English is not my first language, but I like to write in English. Where do you think I went wrong?

"Hey, Lule. Did you remember that I sacrificed my whole night for you? It means you're precious to me. But we won't meet again. Don't worry, I won't forget you.."

(Lule is my father's ex-wife's neighbor's dog..)

I'd appreciate it if you wouldn't be offensive to me.
