Jaania don't worry there's plenty more still waiting from 2009 and 2010 before you:
Husband Cases still waiting for PPR or in interview queue
2009 cases: M2009, resham, BLOOMINGFLOWER, amnafahad4life
2010 cases:man_cub, Nousheen1,soniagak,saggit19 & saggit_16,Coolperson,Shahrukh Sani, dante2010
There are also some wife cases that are also waiting. But at least you know you are not alone in the waiting queue. In sha Allah your wait will be over soon and theirs too. From the review it sounds like they should now waive your interview if the genuine relationship is the concern to them.
