oh, I don't doubt that she has hey eye on someone already... It is often the case. It is hard to abandon your family unless you have a crutch to get through the hard times. This is good that the hurt she is causing you doesn't last as long anymore... This is detachment. You are beginning to gain control of yourself.
Shaves, are you aware of boundaries? I will give you an example of how you can use them in your sitch to show that you respect yourself and it will also gain respect from her at the same time...
Basically you want to use this format When you (talk to me, treat me, act like this....ect.) it makes feel (whatever way you feel).... It is a personal statement saying how others actions affect you.... It is your threshold of how you will allow people to treat you..... A boundary is where you end and where someone else begins.... Someone that doesn't respect your boundaries gets put back in their place.. Walk aways will test your boundaries and if you stick firm everytime, you will TEACH them how they can treat you.
example
W- calls you up talking in an inappropriate tone, yelling, out of control, wanting you to do something. S- W Listen, I have no problem talking with you and trying to figure out a solution to this, however, I don't appreciate the way you are communicating with me, give me a call back when we can have a more reasonable conversation.....click... You are in control, you don't get suckered into an argument, you show her what is acceptable, you decide what you will tolerate... This shows you respect yourself.
Sometimes you just have to listen and validate, sometimes you have to own your crap behavior, sometimes you have to tell them like it is.
