Unsure how to properly list supplementary travel as a spouse (I'm the sponsor)?

[TrainWhistles85]

Hi everyone. My wife and I are going over the form IMM5562e which asks for the principal applicant (Her) to fill out all the countries he or she has been to in the last 10 years. This part we understand ok. However there's also a section for the spouse (Me, in this case). Do I need to fill this out even though we haven't yet traveled out of country together? There doesn't seem to be a clear indication of what it's asking. I've undertaken 4 trips abroad to visit her so far, but I was the only one traveling and I am the sponsor. If someone could please help make sense of this we would be very grateful!

You also have to list all the countries you've travelled to in the last 10 years (with or without her).
