Post-Script to Many Happy Returns

I don't really even know why I'm so upset about the engagement. I'll always love her for being the only ex-coworker from "Main ex-Employer" to show up to my sister's visitation, but I'm not really as "in love" with her as I was even this time last year. I think I actually do know the reason why I'm upset, I'm just having trouble putting it into words, as I often do. I figure that the reason is pretty obvious, you'll figure it out, and will say it better than I could.
