Those who obtained their green cards via marriage to a USC are also restricted by the 5-year waiting period, not just F2A spouses. And the OP's marriage ended in divorce, so the widow exception doesn't apply. So that leaves only the option to provide "clear and convincing" evidence of a bona fide marriage, which is not a trivial task especially if it's barely a 3-year marriage without children (OP didn't mention children or lack thereof or length of the marriage, so I'm using "if").
But for all practical purposes the 5 year wait specified by that section of the law is moot, since the OP can't obtain citizenship before 5 years anyway and her future spouse can't apply to adjust status before she becomes a USC.
Maybe I did not make it clear in my prior post, for that I beg pardon.
The prohibition is based on the type of I-130 being filed now.
If an LPR got their LPR status as a spouse of a USC or LPR then (s)he cannot file an I-130
as an LPR for a new alien spouse (that would be an F2A I-130 spousal petition) UNLESS,
(s)he naturalizes because (s)he will be filing an IR petition as a USC petitioner, OR
is widowed from the USC who petitioner for him/her, OR
the LPR proves the
bona fides of his or her own greencard marriage, OR
5 years has passed since the LPR got his/her initial LPR status through marriage to an LPR or USC.
This statutory change was made to guard against something that was happening but was found out.
LPRs were immigrating through marriage and then staging fraud divorces and marrying their former brothers-in-law or sisters-in-law (sometimes cousins too), immigrating them, divorcing again, and then re-marrying their REAL spouses whom they NEVER stopped living with during the temporary fraud marriages.
Flatly stating that one is not allowed to file a spousal petition for 5 years is incomplete information.
