"was"

I'm so unnerved at the past tense of people's relationships. Having never had a personal experience myself of having and losing someone important, I can't imagine how excruciating it could be moving from two to one. What baffles me further is how some people can move on to the next person so quickly. Especially people who I know, whom I had been acquainted with. I think it disturbs me more than it does them. In my mind they were one half of a partnership, and it feels foreign to me to see them otherwise joined with another entity. And of course it's none of my business and I am no one to judge, so I am not judging. I am just saying that somehow I feel that loss so deeply even though it is not mine. I feel like my heart is leaking tears.
