I have been experiencing that too. Sometimes he just doesn't give me what I need, what I want, and then I think it's proof that he doesn't care about me...so I push him away, I don't really need him right. Then everything he says or does seems to push my buttons. Even though I should know better. It usually gets better if I am as open as possible with him about it. I do need him. I think he does care about me.
