Great words of wisdom here and I'm grateful to all that shared.
I just want to add that you don't have to determine TODAY, right this minute, whether or not she is lying, etc. If she is lying, it will become very obvious very quickly, right? Then you will be able to move on for sure.
Removing toxic people from your life is a very healthy step for you and I applaud you for those decisions. Yep, it's going to be hard for awhile, but soon you'll be blessed with a healthy recovery well underway and new, healthy friends to walk with you. Congratulations!!!
