Adjustment of Status - I-485

Well I must say its been a hectic 5 months period for me and my wife,first I got my ead even before I did my biometrics be cuz the post office returned it as undeliverable.
My interview was in Phoenix on 1/19/2015
After just a 15 minutes wait the officer walked us in ,we swore an oath,dang the interview started.it was all cool at first,she just asked about questions on our forms we filled.the tough time came when she said our age difference was huge and she needed to separate us for questions.i really felt uncomfortable.i had to sit outside .after like 20mins with my wife she invited me in alone too.asked questions like
Who pays the bills
When was the last time you had sex
Who drive the car here today
What was for dinner yesterday
Who and who stay in your house
What's your apartment colour and what flooring is it made of
Does your wife take birth control pills
What type of toothbrush do you both use and your bed size
Wha colour of your comfort sheet and do you guys share the same blanket
Who cooks?
After that she invited my wife in to join me and told us congratulations your application has been approved
I felt like crying ,it's been a busy road down to this point.i should get my card in weeks she said
Goodluck guys
