I went to see the movie this evening and, well, I get it. Guys don't mix their signals they just give you excuses for not being into you. For example, "You're too perfect", "Too successful/awesome", "I just got out of a relationship", "I'm not emotionally mature", "I need work on myself", blah, blah, bullshit. I guess its being considerate and saving a girls feelings, but maybe they are just too afraid to say it.
