What does it mean if a guy says he has a girlfriend?

When a guy tells you he has a girlfriend it could mean he is: Giving you a signal to back off. Turning down benefits at work from a superior in return for a sexual relationship. Proposing an invitation to be the girl with whom he is cheating on his girlfriend.

How do you respond to a guy who says he has a girlfriend?

Simply smile and say “lucky girl” or “my loss.” Thats it. Enough said. If you think theres potential to become his next girlfriend, then make sure you fill the friend spot while he remains with his current one. Keep talking, flirting and asking questions about him to hint that youre interested.
