Your main obsticle is the Affidavit of Support; your I-485 requires one, from him.
There have been other spouses in similar situations who have applied for I-485 on their own.
#1--your husband has filed an I-130 petition on your behalf; it has been established that you are legally his Immediate Relative and you are eligible to Adjust Status..
#2-you have been married to a US citizen for +2 years. This is the 'fraud cutoff' timeline established by law, and the length of your marriage pre-supposes that you did not enter your marriage solely for the immigration benefit. This opens a route to self-sponsorship (but you have no income)
#3-A case has been made that refusing to complete the paperwork necessary for your immigration is a type of abuse, opening up the doors for a VAWA self-petition. Again, the length of your marriage works in your favor for this.
An Adjustment of Status was recently granted to a widowed woman based on simply criteria #1; this has opened up a new line of defense for women who have been put in yoru unfortunate situation.
Clearly I don't know a lot about this, but you may want to start seeking out different immigration lawyers that advertise VAWA and work with abused women.
Of course, you need to strongly consider why you would want to fight this. You haven't had an opportunity to integrate into the US, you have no income, no means of transportation and how much fmaily, friends, support do you have here? It may be the better choice to simply go back to the PI.
If you want to stay, I'm afraid you have to do some serious homework, and you're going to need help. Organizations like Catholic Charities help immigrants for low or no cost.
