What does love have to do with it? In the beginning when you pick a guy not much. It's all about chemistry in under 30 seconds. This is a decision your body makes often to your complete surprise. There are guys you wish you had chemistry for and guys you wish you didn't. Watch the video link below to see what's happening chemically when your body chooses a guy when dating and how to select the right boyfriend.
If you're not happy with the choices your body is making when picking and dating guys and it's causing you pain and disappointment do what I did read A Life Of Love because we always pick the right wrong person until we get the lesson.
When you keep picking the same kind of guys that cause you pain; you may like myself unknowingly be a norepinephrine addict aka a pain addict. Once you are aware you can start to make different choices and choose guys that feel good and treat you well.
The biggest decision we make in life is who we love. This is the difference between a great life and a painful one. Once you understand why you've been making the choices you've made in the past you will be ready to take the steps to make new ones. The key is to select the right boyfriend. I suggest watching Chemistry to Commitment.
