The "bonds which hold water molecules together" are, I think, the covalent bonds holding the Hydrogens to the Oxygen.
Evaporation does not break those bonds, it's just the intact molecules energetically escaping the surface tension of the liquid.
(Disclaimer: My high school chemistry books have not left their shelves in many years, except when moving.)

"Surface tension in water owes to the fact that water molecules attract one another, as each molecule forms a bond with the ones in its vicinity."
Surface tension is a bond that binds water mold together similar to how mortar holds bricks together in a wall.
Mortar doesn't make the brick solid, but it holds the bricks together.
People are reading bond in two different ways. Bond within a molecule vs bond between molecules.

Hmm, could you call this mysterious "cohesive attraction"
> the bonds which hold water molecules together.
...? If not, then please do describe this cohesive attraction.
I've come to realize some people just like to complain on the internet.
