Is not giving after care a red flag?

I had put the only good dom I have come across on a pedestal, I was healthily obsessed with him and couldn't get him out of my head even 4 months after we stopped talking (we only spoke for 14 days and met once) - I am not someone who thinks about someone for this long after things end. I loved our experience, and he was the perfect dom during. It was my first time having a proper bdsm experience, I was his service sub during - knelt for at least 3 hours and more - walked on fours to serve him and his orders, there was face slapping and spanking and nipple torture, lots of - ridiculous amount of degradation involved too. I loved all of it. We had over an hour left after we were done with the session, throughout which I knelt in front of him - watching him work or talk to his ex/current subs on call, he also talked to me without sexual innuendos, just as people. He had plenty of time to offer aftercare, I really wanted it, but I didn't think I had the right to ask. Although, while traveling back home I mentioned how he didn't give any aftercare and that the only way I would listen to him talk was if he held my hand - jokingly, and he did. Would that be considered as after care? He said he didn't do enough damage for after care, but it was my first legit experience.

I have come across videos of aftercare and I crave it so much; I've never experienced something like that. Basically, my obsession over him was unnecessary, right? Because he wasn't really a "perfect" dom after all.
