Five Reasons He Might Not Be That Into You:

One of the most irritating aspects of dating is when you've been casually dating someone . . . things are going well . . . and then out of nowhere they suddenly lose interest and disappear.

–It's tempting to make excuses for why things went south . . . and you can rationalize it however you want . . . but here are five common reasons he just might not be that into you.

#1.) He never really WAS into you. You were thinking relationship, but he was just thinking hook up.

#2.) He found someone he's more into. Maybe that coworker he's been interested in suddenly left her boyfriend. It happens.

#3.) Your friends or family scared him off. Maybe the idea of you someday turning into your mother freaked him out.

#4.) You nagged him too much. Anytime you asked him to do something more than twice, it's no longer a reminder, it's nagging. Even if you feel justified, it still irritates the hell out of guys.

#5.) You aren't the same woman you were when you met. Have you traded in your tight jeans for sweatpants? Would you rather watch "Dancing with the Stars" than get-it-on? He might've just lost interest.
