Sorry about your marital problems. You should always try marriage counseling. It may save the marriage and shows good faith in trying to maintain the marriage.

Your wife can certainly report you to USCIS, but only the USCIS can revoke your PR. You should prepare. (1) file for a replacement I-551, as a never received card. Pay the fee, do not opt for the fee waiver, as there is not tracking number generated. (2) gather as much information and documentation of your marriage. Print emails, write down the names, addresses and phone numbers of anyone that knows your marriage was bona fide. Family members are good, but neighbors, co-workers and more casual contacts are actually better as their affidavits are more credible as non-self-serving.

Were you granted conditional residence or regular permanent residence? If conditional; you can remove the conditions is you are divorced and have evidence of the bona fides of the marriage. This includes evidence of cohabitation (living together as husband and wife) and co-mingling of assets (shared income and expenses).

If you were granted regular permanent residence, you can divorce and apply for citizenship after you have been a LPR for 4 years, 9 months, generally.

Consult with an experienced immigration attorney, good luck.
