I used to be attracted to hot heads. They are exciting, vivacious, active, outspoken, constantly moving, fun to do things with. But, as I came to find out, they are horrible to date long term. Too much drama, all the time. Let your guard down for an instant and they are eating your spleen for breakfast.
Now, I'm attracted to the nicest people I can find. Hardly anything is as attractive as a smart, educated, intellectual and beautiful girl that is humble, human, understanding, compassionate, and thinks I'm the greatest thing that ever happened. I like having that standard to live up to every day. I'm turned off by people that complain or say nasty things. Shrinks my weenie every time.
If you're worried she is going to bite your head off, then run the other direction, there are too many out there to share your valuable time with. Unfortunately it's a numbers game, you need to know that, but try not to let that jade you. Each person deserves your attention and respect to see if there is anything to pursue.
