Unfortunately, since you entered the U.S. illegally, you basically have three options:
1) Wait for an immigration law to come out that will help you. I have high hopes that this year or maybe the following, something good will come out. There is nothing out yet except what I will discuss near the end of my answer. But believe me, when something comes out, everyone will know about it. It will be all over the news and if you have any doubts, you can always come back here and ask about it to see if you qualify. But for now, no sense in worrying because nothing has come out yet and whatever is on the drawing board will undergo so many changes that what it looks like today will probably not be anything like it looks like when it is finally passed. So just be patient about that.
2) Apply for Asylum (you had to have done this within the 1st year be being in the U.S. unless there are changed country conditions), Withholding of Removal, Convention Against Torture, or Cancellation of Removal. The first three things are if you fear to return to your home country because you believe that you will be specifically targeted due to your race, religion, nationality, social group or political opinion and that you run a high risk of great bodily injury, torture, or death as a result. The last, Cancellation, you would have to prove that you have been at least 10 years in the U.S. AND you must also prove that if you are deported, a U.S. Citizen or Lawful Permanent Resident that depends upon you will suffer exceptional and extremely unusual hardship. This hardship must be something more than emotional separation hardship or financial hardship, so it is difficult to get.
3) If you marry a U.S. Citizen (for love, of course), you could file an I-130 here in the U.S. (which will give you no legal status), but once that I-130 is approved, really the only thing you can do is leave the U.S. and apply to come back in at the U.S. Embassy/consulate in your home country as the spouse of a U.S. Citizen. At that point, they will want to deny you because you entered illegally and stayed. So you would have to apply for an I-601 waiver (forgiveness) and to get this waiver you will have to prove that your spouse will suffer extreme hardship if you are not allowed back in to the U.S. These waivers are very difficult to get. The reason they are difficult to get is because your spouse's hardship probably will need to be more than just economic hardship or emotional separation hardship. So because they are difficult to get, no one wants to risk leaving the U.S. and getting stuck outside for 10 years if it isn't granted.
You can look at this link to get more information on I-601 waivers. It is from the U.S. Embassy in Syria, but it is a good description and the process should be similar in all U.S. Embassies.
and here is another link:
And here is a link to what extreme hardship is:
And about Obama's new law, it isn't a new law. It is a new procedure but I think it is a trap. Why? Because right now there are millions of undocumented persons in the U.S. that are married to U.S. Citizens and even have U.S. Citizen children but they do not leave because they are afraid to be stuck outside for 10 years. What has changed (or will change in March) is that before, a person had to leave the U.S. and spend around 15 months or so while waiting for their appointment at the U.S. Embassy or Consulate in their home country and then HOPE that they got approved, but the change is that now they say that the same person can apply inside the U.S., supposedly get a pre-approval, but they still have to leave the U.S. and present themselves to the U.S. Embassy or Consulate. So why do I think it is a trap? Because it could very easily be a way to just get those many millions of people to finally leave the U.S. and once they are outside, they can still be denied the waiver even though they have a "pre-approval". I just don't trust that. So at the very least, I would wait at least 6 months or more after they implement it (which is supposed to be in March of this year) to see how many of those pre-approvals turn out to be true approvals at the end and to see how many of those people actually come back. Here is an official link:
Keep in mind, that in order to qualify, it is ONLY the hardship of a U.S. Citizen or U.S. Lawful Permanent Resident spouse or parent that counts. The hardship of children does not count.
