Is it true that once you grow accustomed to someone's presence, you also miss them more when they're away?

My boyfriend and I had been dating for a year and two months prior to moving in together this June. Today I had to go to my hometown for a while and as he was seeing me off to the bus that would take me there, he said he's actually more sad because of me leaving now that we're living together than he used to be when we just saw each other once a week. He said that he could easily resume his other activities after our meetings in the old days, whereas now it makes him gloomy to see our shared room empty and to go to sleep without me. For me it's actually quite the opposite. I used to be on the verge of tears every time we said goodbye because I wanted to spend more time with him and due to our conflicting schedules it was nearly impossible. However, now that we share a place, I am able to go to other places relaxed, knowing that I have our shared place and him to come home to.

Has any of you experienced something like this? Which point of view of the two would you have more likely?
