I have 'flashbacks' like that a lot. Something he told me about 'them' or something I read, something I heard...sometimes I push past it and other times I think on it for a while and it makes me cry. I sometimes wish we had those mind-eraser things from Men In Black to erase some of the details...
I do want to be able to love someone with my whole heart again someday, but when/if that happens I will not be so willing to give, give, give unless the other person is also doing the same.
