TM, I agree w/AJM...you are spot on in taking care of your little girl's best interests.
Yep, MLCers will call upon you and think you are absolutely wonderful, but when their mini crisis is over, you are right back on the castaway pile.
I'm sorry she's treating you this way. It's uncalled for.
Take care of yourself and enjoy the time you spend w/your little one.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
