I've been reading his poetry lately, came across this gem on postwall women:

Now she desires no more: do you too, weakling, not desire;

and do not chase her who flees, nor live in unhappiness,

but harden your heart, endure and stand fast.

Goodbye, sweetheart. Catullus now stands fast:

he will not look for you or court you against your will.

But you will be sorry when you are not courted at all.

Wretch, pity on you! What life lies in store for you!

Who will come to you now? Who will think you pretty?

Whom will you love now? Who will people say you are?

Whom will you kiss? Whose lips will you bite?

But you, Catullus, be resolute and stand fast.
