Why are protons and electrons not pulled together by each other?

They are, that is why atoms form: The electrons become bound to the positive charge of the nucleus. This happens because opposite charges attract. Now, they don't crash together because quantum mechanics restricts what kinds of orbits are allowed. Though take the word "orbit" lightly as electrons don't orbit in the same way the Earth orbits the Sun. Rather the actual position of the electron isn't fixed, and you have a probability distribution where it can be found.
