It's often said that in personal relationships, opposites attract. Well it could mean that this is true only up to a point - close relationships between opposite characters are repelled - opposites keeping their distance. What is that repulsive force again?

What has this got to with gravity?
Your link refers refers to the electrostatic (Coulomb force) between a positively and negatively charged
atom which form an
ionic bond.
Bring the atoms in closer and the electrons from each atom repel each other. The zero point for force occurs when the repulsive force equals the attractive force. The magnitude of the attractive force is at a maximum when the repulsion force is at a minimum. Separate the atoms further and the Coulomb force decreases as the inverse square law for distance.
