I'm am glad you found this site, and glad we can offer some advice. It is sad that many of us have seen similar scenarios and why we are all telling you the same thing. It happens far too often, and men and women like you fall prey to ppl like her. She will bring on the big crocodile tears, beg you for forgiveness anything to make you feel bad. Anything to get back into the house with you or just keep stringing you along to have you continue to get her that GC. Exactly like she is doing to you now. She thinks because those came in soon she will get the GC. She doesn't know you sent in the letter to withdraw. When she finds out it will get ugly.
You are so worried about her getting deported even after getting her SSN and EAD. You need to close your heart off, you are not protecting yourself enough. Get angry, get upset, get mad and stomp up and down. Close off your heart to her. I'm not saying go make her life a living (you know). I'm saying back away, and let her chips fall where they fall. Serve those divorce papers, and get far away from her. Block her number, before you lose more then your job and housing.
