You need to date different sorts of girls. The problem with many men and women for that matter is that they keep dating very similar people. Obviously for whatever reasons they are attracted to a certain sort but how many times do they need to make the same mistakes before making better choices? Not all women or all men are the same. If you find that all the people you date are much the same it's because you're dating people who are pretty much the same. Try something different!!
Watch how they treat animals, family and people who can't do anything for them.
