Its funny because I was on a date last night and the chick (that I have known for about a year) told me how most guys are super needy, act butthurt if something really does come up and plans change, etc.
She looked me right in the eyes and said "You are totally different. You are independent and you understand that I am a busy person and have limited time to date because you are a busy person with limited time to date". She went on and on about guys blow her phone up, sending 4 and 5 texts without her responding.
If a man wants to separate himself from the pack its pretty easy. Dont act needy, jealous or desperate. Be FUN but be indifferent. Have your own life for crying out loud.
