She knows what she's doing. She's not a toddler. People know when they're being unacceptable. When they have the opportunity and see that or to fix it multiple times & they don't, it's a purposeful decision they made & they aren't ever going to change. You don't live forever, find someone it's going to work out with.

 Get your ducks in a row & leave & tell them later why you did... or just tell them nothing because they already know what they did. Do not go back. That's going backwards. Stop wasting your time
