I'm sorry, I know how dishearting this is for you. I dont know why they talk out the side of their face so much, re-wording past convo's. It's even harder when their actions 'seem' positive only to find out they were more neutral.
And like you said sometimes you have to backslide to get the real view of things. Remember, act as if, maybe it's time your not so available to H???? maybe time to be a tad mysertious.
