I also received a short form at 58 years old. I am on a 3 year diary so i should have gotten one at 61 but have still not gotten one and will be 64 in a week. From what i have been reading at another site it is rare to get one once you are over 60 unless you are working close substantial gainful activity,

Hopefully you both hear soon and there is no drama. Many people are waiting much longer than usual in receiving decisions on short forms and long form cdr's
