WW Patience, Limbo amd Fear

[Core]

Id have more patience if I had more incentive to keep her in my life. She treats and treated me badly, withheld affection and intimacy often, makes fun of my interests, didnt spend time doing things together....the list goes on. I ask myself often now...why would I want her back?

Now I found out, she is contacting some friends telling them lies about me. For example, she told them Im in a massive panic over being work at home now. Im happy to be at home and Corona gives me no fear. This is something shes done for awhile...she makes up how I feel instead of asking me, then tells others her assumption and is validated for putting up with so much. She told someone that she is "doing alright but is still unhappy". Well of course!??! Youve done nothing but avoid the situation yet you think it would change or that I would crawl back to you?

Im not sure why I'm still stalling. I know what I have to do. I think I just dont want to be the one to do it.

For the time being...how do I set a boundary when she makes a disrespectful face? She does it often, as an example, I mispronounced a word which apparently disgusted her to the point of her needing to make a face. How would I enforce a boundary when shes got nothing to lose?
