Hello, my name is ***** ***** I will be the immigration attorney helping you today.
I am so sincerely ***** ***** this has happened to you. It is awful and no one should have to go through it especially when you are pregnant. Unfortunately I'm not going to have very good news about this, but I do have to be honest. I can explain what will happen and what happens with the options and then you can decide what to do.
The only way you can self petition your green card at this point would be to file under VAWA (violence against women's act) which means you have to show that you have been abused by your husband. Unfortunately cheating and squandering your money is not enough for a VAWA petition even if you are pregnant.
If you continued with the application with your spouse and somehow were able to get your green card, even if you did not remain married very long after, then you would very likely get to keep your green card permanently. However, you would need his tax returns from 2015 and you would need the 2015 taxes from the joint sponsor along with their W-2 and proof of US status.
On other hand, yes, if you withdraw the petition from your spouse, you would likely face deportation or you can remain here without status.
Again, I'm so sorry there are not better options. I hope you can understand that I don't make the laws and I cannot change them.
Good luck to you and I hope this answer has helped you!
