Um, no, he's regretting, and likely focusing way too much on what happened and how he reacted. It's both of these that he's regretting, by the way, and he's so focussed on them that he'd not seeing the positives, just potential negatives.
The thing about the Moon combined with this is that the moon is *moody.* It's not stable. You can be lost in romance one minute, then thinking it's all illusion and dream the next, then feeling cold and distant and lost the next. bad All-in-all, I'd say that this poor guy is very mixed up about his feelings towards you. On the plus side, he certainly feels something. On the negative, he doesn't trust what he feels. He doesn't know if what he feels is good or or if he should be happy/unhappy about what he did.
Like the Moon, you can't trust how he's feeling at any given moment, because it's likely to change. Which means you're doing the right thing in backing off. I'd go so far as to recommend you back off even further--don't talk to him about it, don't mention it, don't message it, don't say much to him at school. Give him space and time. And don't ask the cards this question again the research is over and he has had time to really reflect on what he felt and figure out what he wants. Let him get out of the dark and into the light of day. Then you can find out if he wants to go any further.
