I hate when I am writing something out and then someone flounces
So I will answer your question:
Of course you were always in a relationship, but
According to the entire etiquette idea of , "You don't have to give single guests dates, you only have to invite significant others", then your relationship did not count as a significant other. You were not engaged or married, and you were living together for convenience.
If I, personally, was inviting you to MY wedding- I would invite you together as a couple. But I would not consider you as "Significant Others". It would be more of a "Social Unit" thing.
Significant other = spouse or spousal equevilant .
Single = unmarried.
that's that
No, we were living together because we loved each other and wanted to get married one day. We stopped living together because we thought it was important to finish our educations before we got married. It's why we will have been together 6 years by our wedding day. Of course we could have gotten engaged as soon as we decided we would marry each other, but I didn't want to be a teenage bride without a degree. Most people would say that was a wise decision. You, apparently, think it means we weren't significant others.
Sure, we stopped living together when it was "inconvenient", but a round trip commute between our schools would have been 11-12 hours of driving every. single. day. The fact that we were willing to do that should show that a couple is extremely serious, because you don't continue a relationship that will be long distance for some time without being serious.
