Have you told her any of this? Have you said 'I need x, y or z to feel valued'? Have you said 'I'm not happy' or 'I'm depressed'? If you don't say she can't know. If she can't listen, it's a different issue.
I know that a portion of those of us on the spectrum need to be told what our partners need and will not know if we're not told. Hinting is no good, hinting will not be understood, being blunt and clear about things works best.
In a relationship there is supposed to be give and take. Suppressed childhood issues seem to be a big thing here, also that you said (forgive me if I missunderstood you here) that you suppress your own feelings which is not healthy for either of you.
My suggestions on this is to try talk to her about this, in this talk try to explain that this is serious and that she needs to listen. Understand that while there are issues with AS/NT relationships, the biggest issue here may be the childhood abuse. A lecturer of mine has said 'memories buried alive never die' a lot, it means that if a trauma is not dealt with, the person will never really get over it.
How do you feel about her? This is important to think about. I also think that you getting councilling may help but know that finding a good one is hard. It will help you get your head straight and if you think this relationship is fixable, it will help you get her help. I hope you choose what is best for you.
