I think the only expectation you can have is to expect the worse from her behavior. Yes, she is self-absorbed, selfish, short-sigthed, etc. and that is par for the course. Watch the expectations though, they create dissapointment, anger and resentment. If you are going to continue in limbo-land for the foreseable future, those negative emotions are not good.
Having said all that, it is sad to hear S7 so hurt. Tragically, you can expect a great deal more of that.
Your GAL is great. It is great for the kids as well. You are doing the best you can under an extremely bad situation. There are those who say that adversity does not build character, but reveals the lack thereof. You sir, have an abundance.
