how could someone be so close yet so far?

"he's so close, yet so far. he's beyond reach now yet i could still feel his skin lingering on mine. but he's not here, not with me."

physically he's here. yes, with me. but deep inside i just feel we are miles apart. he never talked much anymore, i mean he just went home and greeted me and went to bed. i don't understand why, he might be tired though, but at least...please...i'm here. you used to say that i am your home but now i don't feel i am anymore.
