<human>: My girlfriend of 3 months is older than me, has only dated guys older than her, tells me that I'm not socially mature, and not dependable.  She cant explain, and doesnt want to tell me how to act, just that I do it on my own;  also that it will just take years to happen.  But it seems it only has to do with my age... I take care of her as best I can, and would do anything for her.  I am a rather shy and unconfident person, but she says its not about that.  So how do I make her see me as a stong, dependable boyfriend?  Is there nothing I can do but wait?

Can you condense the text into three sentences or less?
