Honestly I would stop doing things with her. She is cake eating. She has friend zoned you. Thats my opinion.
The more you stay around her, the harder it is to detach. So the longer you keep doing things with her and acting like her BFF, the longer you will stay hurt. You will notice that you are detaching correctly because you will feel better emotionally.
Remember, detaching is for your emotional well being. If your WW starts to ask why you are detaching, just tell her you are focusing on yourself. She will notice and she will either fill the void left with hate or with temp checks.
is it good or bad if she fills the void with hate and/or temp checks?
