I think that it's possible to get a green card if you
may keep the marriage ,even you already sepayated.
Different to the immigration application based on the marriage with a US citizen,your marriage was built before he filed I-485,as previous experience,USCIS usually won't doubt the marriage is fraudulent & only for immigration intent,if you may give their a reasonable explanation & some evidence.If you have
divorced with him,nobody may help you,even I-360,because it is apply to US citizen & PR's family
members.
