How do we know that 2 stars attract eachother instead of repulsing eachother? What proof is there?

A simple force diagram and momentum line diagram provides the proof; repulsing stars will fly apart in very quick succession, whereas an orbit can only be explained by an attractive force between the two orbitting bodies, be they a planet and it's moon or two co-orbitting stars in a binary system.
