When I was just a little bit younger than you, I had a girl that I thought was the love of my life. Then I turned into Forrest Gump. I love you, Jenn-nay! Why are you running away Jen-nay? That was fifteen years ago. She is still really awkward about even talking to me, because she's afraid I'll act the same way. She sends me a drunken facebook message occasionally, then won't respond when I respond. She's taken care of herself really well and still looks good, but I really don't see her as that hot anymore. It would be too easy to get a girl half her age for me to think of her as that hot.
That's what happens as you go from your 20's to your 30's. Women your own age become less attractive compared to the younger crop.
