This is the best bummer jam. I don't think it's stalkerish, but obsessive. It's not that he's literally waiting for her outside the bar, I think he means that once she's through with that whole scene, he'll be there ('to get back into your life'). Needless to say, that's just pathetic wishful thinking.
does it sound like there's some creepy stalker motif in this song? "when you get out of the dating bar, i'll be here to get back into your life" suggests that this girl is looking for someone else. and shit, why is she in the hospital? very weird and angsty, but i totally love the song
