PARAPHRASE:

First quatrain:

There are a lot of different kinds of guys—as I have heard and as I have seen—who are in the habit—when their ladies begin to have other interests in other guys—of moaning, wailing, and generally going on and on (in the fine, sappy, sickening, traditional Petrarchan style), hoping all that (pissing and moaning) will make them feel better.

Second quatrain:

And there are other dudes (just as dumb) who—when it happens (as it always does) that women change their minds and start hating those who they had loved (like a millisecond ago)—start calling them sluts and (at the same time) try to talk them back into love (fat chance of that ever happening), even after the women's hearts are set on someone else.

Third quatrain:

But as for me, though it may happen (and has) that a woman's changeable heart discards the fancy that she used to have for me, I will not wail or moan, or even be (even a little) depressed; or call her a slut that used to feed me with hope of eternal bliss

Concluding couplet:

But just let it pass, and remind myself it's the kind of thing that is natural to women, because frequent changes please a woman's (freaking) mind.

TONE: cool cynicism

Below is my "I"m cool with it, babe" face which you may gaze upon as I say my sonnet:

Divers doth use, as I have heard and know, When that to change their ladies do begin, To mourn and wail, and never for to lynn, Hoping thereby to 'pease their painful woe. And some there be that when it chanceth so That women change, and hate where love hath been, They call them false, and think with words to win The hearts of them which otherwhere doth grow. But as for me, though that by chance indeed Change hath outworn the favour that I had, I will not wail, lament, nor yet be sad, Nor call her false that falsely did me feed ; But let it pass, and think it is of kind That often change doth please a woman's mind.
