Withdrawal of I-864 , Affidavit of Support

[chichorasa]

My wife filed I-485 for the adjustment of status and have received her temporary green card. After that she separated from me and now she is not returning. I want to be able to withdraw my I-864, affidavit of support. Is it too late to do that? She has already received a 2 year temp green card

If you wish to be not on the hook for support, you need an attorney to see if you can withdraw your original petition (not the I-864 itself). Given that the matter has already been adjudicated, this would not seem likely.
