Adjustment of Status - I-485

Its 2 months plus now that i and my wife went for an interview in Baltimore field and its went successufully and the IOS was very nice. He ask us question from the form from begining to the end. And later ask question from me where i propose to her and how we met. After the interview he gave us a white letter stating 120 days as usual but no one was ticked out of the 4or5 collum on the paper. He asked us if we have question but i said i have no question but my wife ask question from him ignorantly that when is the second interview because the letter we went with shows innitial interview. But the IOS says we are through with you guys now that if we need anything again , we will mail u or make a decission. He was so nice. We offer him pix and said he is ok with or our document. Now its 2 months old after interview what should i do? Online status still on interview schedule and 130 still saying was recieve for my wife. Ur advise is needed plsssss as me and my wife are planning of going to my country.
