You have not asked a question. I assume you want to know if you can become a permanent resident. You may be able to pursue permanent residence, but unless you are grandfathered under INA 245(i), you will likely need to pursue an immigrant visa through consular processing. You may qualify for the provisional waiver which would minimize separation from your family. I would recommend a full consultation with an experienced immigration attorney.
