You do know your choices. The least apart is if you marry while she is here on B2 visa and apply immediately for an adjustment of status. Hopefully, interview will come fast; and if she approved, she does not have to go back (or will go back on her conditional permanent residency card). The drawback here is: if your marriage is not recognized by the authorities and she is placed on removal she will have to be defended. In addition, if your marriage is not recognized and her I-94 expire, she will be considered in violation of non-immigrant status with all legal consequences on admission. Even though this sounds attractive, the other options are safer and she will not overstay her visa. Your relationship is relatively short and might bring attention of the authorities. In addition, I would give a little more time to the relationship, to know more if it is indeed a valid one and not for the procurement of an immigrant visa. Bottom line: it is still your choice. Also, you must know if your income qualifies you for an affidavit of support (given that you have a child from your previous marriage).
