Okay let me explain.
I met her my freshman year of highschool and I kinda grew on her and stuff. Yeah okay I was thinking with the wrong head and ended up in a relationship with her. She didn't show that attitude until later on. It still pissed me off though, I mean, if she was as cool as I first thought, I'd still be dating her lol.
Not entirely relevant, but I had a best friend who change from coolest person you'd know to absolute starfish over a period of a few years. People change, and so do you.
The things you look for in a person aren't matching interests or personality, although those are a good start. You're supposed to look for stability. Someone who is pretty much set on who they are, who they want to be, and you have to decide if THAT is who you want.
Side note: Ignore anything Bisjac might add to this thread.
I personally love quiet girls who are polite, but with them not being outgoing, I'll never meet any. I don't go out of my way to date women, especially after having my past riddled with horrific girls. Two stalkers and an insane bitch. I'll elaborate if you care, but it's not relevant in the least.
