Yes, exactly, I agree completely. She's clearly having an MLC. Even her sister told me so in confidence, as part of her efforts to give me support in this situation. I've mentioned before that her family has always been kind of my "fan club".
This is your sister's way of a labeling it so she can rationalize what is happening. You're good guy and probably did nothing wrong that makes sense for her sister to leave you. If she labels it as MLC it helps her come to grips with it.

If you mean this than you are already a winner and way a head of the game.

This may initially motivate you but eventually you will be on your own journey of self improvement for you.
