Hey HF. In regards to your speculation that he was about take another big step towards OW and wanted to test his feelings for you in first, I say not a chance.

Nobody (certainly no male) plans a next big step like that. They just do it. They fall into to deeper relationships with someone. They don't rationally sit down and say "Ok. I want to amp things up with OW, but first I will test out HF" That's just silly (sorry). If he wanted that next step, he'd take it and not worry about you. This is a WAS were talking about not some trained DB'r.

Much more likely is that he had feelings about you. Like a moth to a flame, he came floating to you. Then he touched the flame and jumped back. We know how moth's work though. He'll be back.
