<human>: Summarize the given text in a few sentences.

Am I just worrying about semantics? I've been dating this girl exclusively (on both ends) since late October. I broached the subject of what she sees me as in mid-December and she said she wouldn't call me her boyfriend yet, "sorry if that's not the answer you wanted." I played it cool because, as I said, we are exclusively dating.

I'm thinking it's just my own insecurity in wanting to call her my girlfriend, maybe? Labels seems to trivial to me, so why do I care so much? I'm nervous to broach the subject again because I'd rather match her level of interest rather than 'chasing' too much, because I've definitely chased girls away in the past. 

Maybe I should say something like "So to you, is there a difference between dating exclusively and a relationship?" Or should I leave it alone?
<bot>: Should I worry about dating exclusively, but not being in an 'official relationship', or is it semantics? Should I bring it up, or play it cool until she does?
