I really like this women we used to be friends but she just like me as a friend actually she hates me cause I threaten her so now I need advice on how to apologize to her

Just be genuine in your apology, most woman will accept it if you really are sorry, and are honest with them.

Personally, I'd say stay away from her.

Otherwise, what is going on?

You really like her....you want to remain friends? Or you want to get out of the friend zone?

Are you still speaking with her and friends with each other?

What did you threaten her with and why?
I mean huge difference between "shut up or I'm going to smack you" vs. "I want more than friends, if we aren't more, then our friendship will be over."

Did you threaten to hurt her? Or did you just threaten the relationship but now want it back?

Why do you want to apologize? What do you want out of it? Do you just want to communicate how you feel? Or do you want her to do something in response like talk to you again, or see you as a potential mate?

Hit it and quit it.

If you ain't hitting it ditch it.

Meanwhile, back in this universe,

apologize and then give her some time and distance.

Well honestly... she only liked you as a friend and you threatened her...

How her life, physically harm???
what..

My advice if you are sincere apology and walk away..

Sorry I can only say what I would do..

If someone threatened me with physical harm or my life I would stay away from them.

Ummmmm. Threaten her? I hope you weren't a douche.

Ummmmmmmmmmmm. He is not in our "universe."

Your advice does not apply. Apples and oranges. Speak the correct language.

Apologize then never show your face to her ever again. lol
