It sounds like your love languages are different, and he's not interested in learning a new language. Not to say he's lazy, bu t learning how to selflessly love someone else is tough, and most couples try to rely on the old 'infatuation' to get them through their marriage, without any work.
Did he have a rough childhood? What is his negativity coming from? My wife had an ok childhood, but a mother who was verbally abused by an alcoholic father, so I think mom passed some bad traits to daughter. How I'd long for a wife who would want to hold hands, hug, kiss, and want to spend time with me! She's never really done that.
How's his self-esteem? Is his weight in check? Was he picked on as a kid? Lose a sibling or parent early? Just thinking of ways to explain why he's so upset all the time.
I'd keep poking around - would a slow drip of an EA/PA be happening?
