What exactly did she say about the relationship that made your feel you couldn't help yourself?
You do realize you are being hooked and reeled in. Back peddle as fast as you can. Say I am just trying to have a nice evening and figure these few things out. I don't want to get into it with you and DON'T. As long as she can get you to fight with her she can justify her behavior in her own mind. I think it would be great if you could get into IC and work with someone on how to not get caught up in that cr**. You are not going to be able to tell he anything about her behavior now or any time in the near future and have her react with understanding.
