(((((((Kiya)))))) wow. I am so sorry that this is so painful for you!
It sounds like T made one mistake that is now a much larger mess! ICK!
And there you are all wrapped up in the middle of it!!! No fair for you at all !!!!!

Why don't you go Sat so you can look at T and maybe T will spend time afterwards with just you to get this mess fixed she made? You are the one who deserves that time for your own healing. Even if it takes her all Sat evening to try to work through it, that was not your fault she acted out that way. But you are suffering right now. I am sorry.
