I think you'd be an asshole for accepting an invite to visit with someone you clearly don't care about anymore who also now has infant/children who you don't want to see.
In the few years since we spoke she’s had two babies by two different guys.
Flavor text, or judgemental? If you disapprove of her life choices possibly quite strongly, then yes please don't bother this woman.
Anyways, you won't an asshole if you just let that already dead friendship stay dead. I dislike children enough to seek out sterilization, so I get it.
Seek out like-minded friends instead and you'll be all good.
I can only keep up the charade around my niece and nephew for our bi-monthly supper visits. I'm a good uncle for ~6-12 hours a month lol that's my limit.
