they have been women who say they have a boyfriend whether you hitting them or not. for example a girl will reject you and say she has BF, or you are dancing and you want to dance with her she will say she has BF. in both case neither of them have one
what's the reason behind this, are you testing the guy?
I think women who do that think that saying this will make them more desirable kinda like the whole forbidden fruit thing. Or they just want to put off the appearance that they can get a man. Either way its wrong to lie like that but I guess I can understand where they are coming from. Maybe they have a low self-esteem. I don't know. haha. I hope that helped you a bit. Or like others said she might not be interested.
A teacher of mine once said, "It's not what you say, it is how you say it." You have to really listen to a female to understand whether or not she's interested in you or not. If she has to lie about whether or not she's seeing someone; she's not interested. If she tells you she's not seeing someone (whether or not she really is); she's interested in you.
It's an excuse to get guys to leave them alone. Think about it if you walk up to a chick and she says she has a boyfriend are you going to hit on her probably not. Two main reasons why she would say that are, your either creepy or she's not attracted to you.
The "I have a boyfriend" excuse to me is acceptable if she really has one, she is not interested, or is just out to have fun. But I think it is absolutely stupid if she throws that up just to see how far the guy will try. If a girl says that to me, I automatically move on because that phrase tells me just that: she either has a boyfriend (I'm not interested in screwing around with a girl that's already in a relationship or one that's willing to drop one guy for the next) or she's not interested in me (I appreciate a girl going easy on me lol). I don't have time for mind games when it comes to girls saying that just to see how far the guy will go or for some kind of ego boost. There are plenty of women out there that will definitely be interested in you without this mind game nonsense...
i hate to say it but girls need to learn that the little lie is not the best way...the best way is to say I'm just not that attraced to u...and just say that and that be it...cuz its still lyeing and yeah it realy herts when a guy finds out you dont...and he then thinks ur a bitch...so yes its the lie he might never know...but still its wrong to lie
