I read "The Rules" and I think it is a great book, but I dont follow it exactly cuz there need to be exceptions sometimes. Cosmopolitan also has some good articles. Acting like u dont like a guy isnt exactly what its about, eventually if a guy really really likes u but u keep rejecting him or he knows u dont like him he will move on. But developing a good relationship based on love, and a deep connection is when you know it will last.
Guys need space, and so do most girls. By constantly calling, being available, and predictible a guy will lose interest, so will girls. I once dated a guy that was soo into me he made me sick and theres no way i could feel attracted to him. He was constantly calling, wanted to see me everyday the whole day, and he even admitted he had not much of a life, thats not exactly a turn on LOL.
A good relationship, is based on two people who love each other, but have there own life, and their own space.
