If I'm strong and confident and act as if this doesn't bother me, then it will just confirm to H that he's made the right decision. He'll think he was right: we just aren't compatible. And the fact that I was able to adjust so easily proves that we aren't right for one another.
If my choices are to be weak and needy or to be strong and confident, I think I've gotta choose strength and confidence. If he ends up using that as justification for his choice, then there really isn't anything I could have done about it anyway.
I do still wish I could get him to snap out of it, but I've finally gotten to the point where I understand that I have no control over that.
