That Sudden Aquarian Emotional Whoopsie

Basically, my Aquarian 'friend' accidentally revealed an, shall I say, altered state of his personality to me which I have never seen before. I texted him while he was in that state and he was furiously replying to my messages. I was cool during the incident and talked him through it. It was through text because our friendship is long distance and on top of that, he's currently on holiday.

However, now that he's back to normal his normal state (but still on holiday), he seems standoffish and has been curt with his messages. Usually, I'll just ask him straight up about things, we'll fight, and then we'll work things out (because we have this understanding that even though we're long distance, we're both not willing to lose this connection) but this time around, I'm hesitating because this is the first time he's ever shown me that side of him. He has never even drunk texted me before because his self-control is quite extraordinary.

I guess my question is, is this one of those Aquarian emotional whoopsies and all I have to do is give him space? And if it is, out of curiosity, what usually goes through an Aquarian's mind as he tries to recalibrate himself?

Any advice is welcomed!

Hug so you want to know how someone should act due to holidays or stress of aqua persona?

The altered state was because he took something and was on a high. I talked him through it while he was coming down the high. I've always been sober throughout our friendship because I don't drink nor do I do drugs. He has been sober too because he doesn't reach out when he's drunk. So this is new territory for us.

I just want to know the possibility of him being cold is due to him realizing that he didn't expect to show that side of him to me. It's a frustrating thing cause as much as I want to talk it over with him, he's still on holiday so I don't want to bring this up now. Therefore, I am choosing to ignore his cold replies for now.
