If your serious with a girl, you won't flirt. If you are and you still flirt anyways, your lame and will eventually be alone because you aren't serious. You will probably never have a serious relationship, and I feel sorry for you. Except if you build a relationship on flirting, be my guest on that one.
I think of flirting as this. GUYS KNOW EXACTLY WHAT FLIRTING IS! You can't admit you were, but beneath the surface when you give that "meaningless" hug to another girl while in a relationship, your trying (and succeeding) in relaying a message of "likeness" not falling under a serious relationship standard, AKA, flirting with another girl. Read above for results.
Come on guys, don't lie anymore, I'm a guy and you know sometimes when you give girls hugs and make jokes with them you might actually like them and are showing it. Don't do this to someone else who might actually care about you. I feel sorry for people who are with flirty people. I understand the whole getting jealous being friendly with op sex, but
sometimes being "friendly" means something more. You and your partner can recognize this.
In conclusion, don't flirt with others IF you are in a
serious relationship. If you aren't, be upfront with them and don't lead them on. Nothing is worse than a person that has hurt feelings, it could prove even dangerous to others and themselves. Let's keep it real people, no more lies.
