At the end of day just like you would not expect a person with no legs to walk and not use a wheelchair, you have to accept yourself as you are not as others are or should be.
As far as trust goes for me to say the least, I never trusted my mother, even as a child, as a baby, my animalistic instincts kicked in that I developed dissociation and ptsd to survive. So I never learned trust in the most basic way but here I am and can 100% confidently say I have trust and love in my marriage so which one is it?
but yet, I do not feel particularly trust in therapy or any therapist and then I learned this wonderful thing:
Trusting I never learned trust and I am who I am and accepting my way of trusting is good enough for me is ENOUGH!
It is like this: everybody (well almost every adult) may have sex but not the same way so trust is like that. As long as I am not paranoid or suspicious or wasting mental energy about what and who, I am trusting at basic level. I do not know how you trust or anyone but I know I trust and my trust may look weird to you anyone else but it is mine.
I feel sometimes what makes us crazy or keeps in the loops is we have this notion that there is only way to do something and if it is not that way, we are not good. I no longer believe that.
so in essence, if your b/f says he trusts you and you think yourself you are unpredictable, you gotta allow him to have that trust...maybe your in-predictability is his kind of trust. Maybe if you were too predictable, that would not work for him...I do not know.
I think how you are saying you are not in touch with reality, tells me you are becoming too much in touch with reality and the reality is ambivalent and crazy and one of the biggest thing in PTSD is wanting control and predictability or even strong belief in in-predictability.
From the way you are typing lately or the topics you are choosing, to me (again my own perception of you) you are becoming more in touch in the shared reality...but that is again my take on you.
That is my conscious streaming for the day...(-;
