Visitors Story: One big personality trait that should end up all sorts of red flags when you're getting serious with a woman is clingyness.
Watch her response when you are heading out for a night on the town with your male friends- if she talks about not trusting you, or even goes as far as attempting to make you stay with her instead, wow.. Look out.
That's the classic clinging woman and the seeming "devotion" will eventually drive you nuts.
You should strive for balance in a relationship, which is something the classic clinging girlfriend is inept at.
