Are you saying that her situation is out of my hands and No matter what us going on with her side I should just continue to do what i am doing? not try to figure out if there is an emotional or physical affair that I am dealing with? Just keep on with my improvements for my own sake
YES! ^^^^^^^^^^^^^^^^^^
I am not saying not to have boundaries. YES - you need those for your own protection. I perfectly understand the giving and giving part too.
You need to protect yourself, and not be taken advantage of, just like the lesson you learned with your brother.
You need to know that - people lie! They can not always be trusted.
And with the first bit of advice that I give you Detach. Believe NONE of what they say and half of what they do.
WHY - cause in all likely hood their is some lying going on.
