Yes, I can understand what you're saying about how and why you felt the way you did.
It's really, really hard to know you're saying something accurate just from a person's few words; however, she has given a few clues, in what she's written, that may be substantive, in that way. I've italicized the areas that seem most relevant.
It sounds like her childhood experiences worked against the establishment of trust, in perhaps some pretty severe ways. Childhood is the time during which trust is to be built.. . . ok, I went from thing to thing trying to get away from my past and my childhood and gave away all of my stuff from it so I wouldn't have to be reminded of those times, I never realized that I would meet someone like you that is as kind and caring , and that I would feel safe again. Overcoming your own personal blockages is for you to have, to feel good from the inside out, It's a gift to yourself, I love you and I don't expect it to be done for me . . .
Giving away everything from your childhood is an extreme act and is significant.
She makes it very clear that you are not, nor were you ever expected to be, the norm in her life. Trust creates a feeling and belief in life and people that basically says, "People are basically good. People are basically good today, and will be basically good tomorrow." From what she says, "kind and caring" haven't been an ongoing, normal part of her life; so, you stand out in that way.
Feeling "safe" is one of our most basic needs. Something interrupted that feeling in her life, substantially enough that she really didn't believe she would ever feel that way again.
So, even though you appeared as the 'knight on the white horse,' you are not what she's used to; you're not part of her 'what's normal.' In that way, you're 'scarey' ~ she's learned to deal with things the way they've been; even though she may not like the way they are, she at least knows what to 'expect.' Her survival mechanisms are probably, pretty solidly in place ~ and you're an interruption in her personal 'status quo.'
She could be experiencing a lot of different things right now. Fear of losing you; fear of how to deal with you in the long run; perhaps, 'boredom' with you and your being so 'nice' [after being used to the adrenaline of 'not nice']; feeling more comfortable with being 'shut down' emotionally [her survival mechanism], as numbness doesn't have to concern itself with anything scarey, new, or different. The list goes on.
However, she may be going through the 'fear of intimacy' dance, that even those who haven't emotionally 'detached,' as a result of childhood trauma, do. Even moreso for those who have
. That's a one step forward, two steps back; 1/2 step forward, three steps back; two steps forward, one step back; etc. ad infinitum [sometimes, ad nauseum 
], until she really comes to believe and accept that she really can trust and believe in you. After reading the excerpt you've shared, my honest opinion is that you will do best for yourself to just wait, as well as go on with your life, in the most productive way you know how. If you have any interactions with her, continue to be your kind and caring self. Now is definitely not the time [if there ever were one
] to throw harsh words and accusations her way. Showing your own consistency as a stable person will mean more to her than anything. It could result in reconciliation; it could result in a transformation of your relationship with her into a good, trusting friendship; or it could result in nothing regarding her, but in a building on your own self-respect.Life is about learning, and this may be one of your own, painful lessons. Perhaps, about how some people are able to trust, and others simply not. It may never come to more than that for you. However, how you deal with this will impact how she ends up feeling about you; and, more importantly, how you end up feeling about yourself.
Well, I've said enough for now. This really isn't Psych 101. What I've said is pretty basic information and knowledge. I hope you can pull something from it that's helpful.
It seems that this is too soon to judge the true status of this, particular relationship. You have solid values and high ideals that are pretty rare these days. Please hold on to them. I hope things will go well for you, Heathcliffe.
