So you lived together at least from Sept 2011 continuously to Sept 2012??Bhie1412 said:last Sept 2012 before i work to hongkong for two years..
And you have proof from 5 years ago of the cohabitation?
Based on the general rule around common-law about long periods apart, you may find it difficult to get CIC to accept including your partner as common-law in your own application. 5 years of living separate is a long time.

For common-law relationships (and marriage), the longer the period of separation without any
cohabitation, the more difficult it is to establish that the common-law relationship (or marriage) still
exists.
