So her behavior is probably less about you and more about her ability to cope in general.
That said, I empathize with your dilemma. While I do think it is beneficial to give others the benefit of the doubt and be accomodating as possible, I had to learn the hard way, that rare individuals will allow me to do all the accomodating and ask for more, while he or she gives nothing and are totally offended at the thought that I might expect him or her to actually compromise and contribute. L sounds much like the person who taught me this lesson. Perhaps, she is not; I hope she is not.
She had a strange childhood because her mom went round the twist for a time and she hasn't fully dealt with that. And she's not a mean spirited person, so I feel bad for the way I'm feeling towards her right now. I'm not feeling that great towards G either, but he can deal with sitting down and discussing what's wrong. I sincerely hope that things improve soon. This is more stress than I'm emotionally equipped for at the moment.
