Do girls play Hard to get to Boys?
If you think you know the answer, leave it here.
Personally, I think that some girls do play hard to get...and it's a shame. Sending mixed signals (or worse, only sending the wrong signals) might make you feel less vulnerable around the guy you like, but it'll do nothing but push him away.
Girls would be much better off if they gave off positive signals instead. If you're not sure how to do that, here are some basic flirting tips that might help.
