He also had a mission he was supposed to be taking care of at Beacon, so he may have decided he had scared Blake enough and it was time to get back to what he was supposed to be doing.

We do know from Beginning of the End that Adam isn't so obsessed with Blake that he can't pull his focus off her and back to whatever duties he is supposed to be taking care of. After Blake left him back then, the White Fang Lieutenant said he'd get her back for him, but Adam told him to forget it and said "It's time I return to Mistral and--" He was taking his focus off of Blake and returning to whatever it was he was supposed to do for the White Fang. This shows that he doesn't have a one-track mind that gets stuck focusing solely on Blake. He can remember that he has responsibilities to take care of and properly decide when to return to those responsibilities.
