Adjustment of Status - I-485

Hello I got married 03/14/14 my husband is a Cuban refugee and we are waiting for his interview for citizenship it shouldn't be long. I have DACA since 2012 and current waiting for Advanced parole to visit ill family and also to fix my illegal entry. I was told by my lawyer to not renew my DACA since it will end on 5/17/2017 since I should have applied for green card at that point does anyone know how long it will take once my application is submitted for my green card to get it.? And does anyone know how the interview process is after being married 3 years? I got married when I was 17 we do not have kids together or separately and we didn't have a big marriage we just went to the courthouse and got married with my moms signature we didn't give each other rings until after being married one year ad we got them at a pawn shop so to be honest we would suck at that part of the interview but we are together for love not for immigration gratification so I am a bit nervous they might see our marriage as something weird because it was spontaneous but it has been the best 3 years of my life...
