Attractive and repulsive forces between atoms

My understanding is that, as two hydrogen atoms approach, attraction is stronger initially but repulsion is stronger at shorter distances.  Taking the simplistic view that protons and electrons are discrete particles, it seems to me that, no matter how closely the atoms approach, there is a always a configuration in which the proton-electron distances can be smaller than the proton-proton and electron-electron distances.  Given this, why should repulsion be stronger than attraction at short distances?
