What to do with a guy who is passive aggressive, resentful and (read inside)?

So guy I started dating has, after the first major issue - do to him not communicate basic information properly, has shown he's a passive aggressive individual that is resentful.

Rather than dealing with issues he says that he's at fault even if the two of us are - and which I've said multiple times - and holds onto the anger, etc.

He constantly texts things - such as the relationship is failing - and yet turns around and says that he wants to move closer. When questioned about 'failing' relationship he says that he is merely voicing this off of my actions when I haven't done anything to indicate such at all (he's brought it up multiple times).

Like I'm trying to make amends and trying to move forwards - past this situation so we can continue and grow - but when he says one thing & a few hours, or hell an hour, later he has an entirely different tone without me provoking such a response it's an emotional drain.

Not to mention hanging onto anger / resentment instead of just simply hashing it out.
