Never again will I date a chick younger than I am, when I say younger I mean like 10/15 years younger.
Why, because they are so full of bs and stupid games its makes me feel more like I'm their dad, rather than a boyfriend.
Before some one says, well it's my fault for choosing to go after females in that age group, I didn't, they came to me, in fact my last three GF's have all be in there early to mid 20's and they all ended after they started playing those stupid mind games, they think an older guy does not realize they are being played.
One plus point for being an older guy. To chick of their age, I'm like fucking YODA when it comes to the JEDI mind trick!
