Brehs, there's always a bottom line to everything in this world. At one point, we have to look at things as black and white. Anything in between is a fukken headache. Either the girl is into you or she's not. It's as simple as that. If you want to make things easier, don't stress going in for the kiss until the 2-3 date. Just worry about picking her brain and finding out if she's damaged goods or the level of insecurity she's carrying. Play things cool and don't worry if you're going to get it in. Like many have stated in this thread, be careless about your feelings. Just don't give a fukk.
After a couple of dates, go in. If she backs off or resists, DROP HER. You're saving yourself a headache. It's that simple.
