I'd proceed with caution. There's much more to this situation than the "is he or isn't he drinking?" of alcoholism. Start looking for patterns over a matter of months and years, instead of looking for patterns over days and weeks.
Your AH shows a long-term pattern of instability and he leans toward emotional abuse when he doesn't get his way. I wouldn't be eager to cozy up to that pattern, myself.
We get so used to one-sided relationships that we are so hungry we'll take any crumb thrown in our direction. And we'll be grateful for it, too!
Edited to add: Isn't this part of his pattern? Free on the phone but frozen and unavailable face-to-face? I seem to recall you mentioning this in the past.
I'm also reminded of the "cycle of abuse" picture we post on here sometimes. My thought is that if you're asking because you aren't sure, it's not real yet.
