I applied for my naturalization at the beginning of October based on my marriage, my husband helped me with the filling and everything. At the end of October he abandoned me because I discovered he was cheating on me. We were even trying to have a baby, I was so pissed off. I lived with him 3 years and 5 months. We are still married. Since November I am living with my sister. My interview is next week and I am prepared to answer that we are not current living together, the truth. I have evidence of the past 3 years (taxes, bank statements, bills, marriage certificate, his birth certificate, etc), we had a genuine relationship and I still love him, but apparently he doesn't.
