Try looking at girls who aren't surrounded by a lot of people, or doesn't look like the "attention-whore-type."
Well mostly girls and guys both have a tense of flirting even if you guys are dating or not. They think cause there not married to you they have the right to do that. But I do think it's wrong on some terms and that they should tell you if they do at least be honest. And try and talk to a girl for a couple months or more to see how they act.
