What does it mean to translate the following English into Chinese?

You're a little strange on and off. I'll translate it to you in a colloquial way (haha, the content is not very serious)

Hello, I haven't forgotten you, because I've been too busy recently. I just heard that Joel found a girlfriend in high school.

I think I can deal with a man as he deals with you. This is my plan.

Honey, I hope you remember me. I sent you a document. I hope you can have a good look. Don't treat me like a stranger. Maybe we can go further.

Look for "fdssgm3005". Don't keep me waiting too long.
