Wolflvr, I'm sorry for the pain you are feeling. Like many others, here I feel the way you do too. We are all at the bottom of that priority list. It's a terrible place to be. But we are there because we allow ourselves to be there. We keep allowing ourselves to be walked over & stepped on. I know we do it because of the good times. We know what good people they can be, but we continue to forget what good people we are. That we deserve as much love as we are trying to hand out to our A's.
Obviously you are the only one who knows when enough is enough in your situation. Just know that we are all in the same boat here. Try to be firm and stand your ground only because you are worth it. You do what you think in your heart.
Good Luck!
