Half stories

I truly feel as if I am going crazy. So much half communications and then fits of temper if I ask him about things later. He will give me snippets of information but rarely the whole story. When I ask more questions he always says he told me all the info. Well he doesn't. Why can' he ever admit that he didn' tell me that. Tons of examples too many to mention....sorry if this sounds vague. It is almost like he does it on purpose.
