Confused

Totally confused today...didn't expect that question to come up. He expected me at the time I told him I was coming in...he doesn't look for me usually naman. Then now..? I wanna take things at face value, that his disposition is erratic. But i can't help but feel and think of something else. He didn't miss me naman, he just expected..eh why would he expect when he doesn't usually expect? Haist. Am I overthinking again? I just feel bad coz I let him down, he expected then I failed to meet expectations. Manhid ba ako, tanga or overthinking lang talaga? :(
