When you were describing your girlfriend, it sort of reminded me of myself and things my husband gets frustrated with me for. I don't know your whole situation, but is it possible that she is just dealing with things the best that she can and in all the chaos, stopping for emotional support is the last thing on her mind, as she is busy supporting someone else. What if she feels like she can't stretch herself around enough right now, between her mom needing her, and you needing her to know that you support her. Please note, I could be so far off on this, I just know that is how I feel when I am in those situations and my husband feels like I am shutting his support out. Its not because it isn't deeply appreciated, its just that it may not be completely needed at that point. Just put the words out there, I am here for you, and when she wants to take you up on that, how fortunate she is to have someone like you in her corner. With all that said, if she is chronically like this, it isn't necessarily a bad thing on her part. You may just be better suited with another personality type. My husband has just come to accept that sometimes I shut him out, for reasons that have nothing to do with him.
