Old habits die hard, but there's Reddiquette which needs to be revived, and some which needs to die.
Many "golden-age" redditors remember a time when downvoting was reserved for hostility, not a different opinion. For the sake of our growing community I would like to implore everyone to be awesome to each other.
However, this place is not Reddit.
We don't measure in bananas here.
We don't need to append "edit: typo" to edited posts and comments.
if you see something which is worthy of a downvote: down vote and move on! Don't engage with it and feed the algorithm/engament machine so other people are exposed to it when sorting by active.
"Look, honey, I know a spot that's great, but we can't go there because I used to go with my ex and I don't like bringing up my ex everytime like my ex did, you don't deserve that because you're more than her"
I think I'd feel weird even if she doesn't know about it. I'd also probably avoid calling her by her name just in case.
