It means he’s not looking to get serious. He likes you, wants to keep dating, but isn’t looking to be your boyfriend. He’s not actively looking around for someone else, but he’s not looking to be tied down either. And he’s definitely not scared. That is such a misconception, that if a guy doesn’t want to get serious he must be scared of commitment. Sure, some guys have commitment issues. But usually “commitment issues” means he hasn’t found the right person to get serious with and/or he’s still looking to date around and not be tied down.
“Not into labels” is usually code for “I’m not looking to get serious with you.” Also, “I might start seeing someone else at some point, and when you ask me about it, I’ll remind me you that I’m not your boyfriend.” Telling you he isn’t into labels is basically saying he isn’t looking to get serious right now. That’s his way of letting you know that you are not his girlfriend and won’t be until he’s ready. (Or possibly not at all.) It’s a way to keep you at arm’s length. Is that a position you want to be in?
Saying you aren’t into labels is pretty lame, if you ask me. The people who say it think they are some free spirit who doesn’t subscribe to society’s rules, man, when really they’re just not being honest. A better tactic would be to say that he likes you, isn’t seeing anyone else right now, but also isn’t looking to get serious right now. The “not into labels” line is the sign of a jerk in many cases. It’s the sort of thing a guy says when you catch him with another woman. “Hey, I said I wasn’t into labels, babe!” This guy is in the driver’s seat in terms of commitment right now. Keep this in mind if you’re looking to get serious.
