@Dorothy Parker,
Does your fella know that you're bored, that you feel lonely, that you feel that you're there for his convenience.
As I read your initial post, it seems that you know what's reasonable to expect from a relationship and that your fella either doesn't know, doesn't care, or has forgotten. It doesn't sound like he's even following the common courtesies he'd give a stranger.
Is he worth talking to about your unhappiness? if so, talk to him. If not, don't bother - other than to get your key from him.
