Birdie, that's why I included in my definition "or other marital event".
"Active" planning is the best way I know how to say that you're planning on getting married. Because a lot of people are engaged, but aren't actually planning anything.
And I remember those people in school, who were engaged, and said they planned on getting married after graduation. And you know what? I never considered them engaged, honestly. Not until I knew there was a plan in place. Maybe they knew, but until I did, I didn't really take their engagement to mean anything. So many women just liked walking around and calling themseles engaged.
This is why I'm not a fan of long (generally 2+ years) engagements. I really do think people should just wait until they are in a place where they can truly, honestly plan their wedding (or their ceremony) before they represent to others that they are a couple planning their life together. Because the truth is, you can call yourself anything you want to. But if I'm not getting the sense that you are actively planning to spend your life together, than I'm just gonna call him "boyfriend" or "that guy you're seeing."
