I sort of meant this post to be more lighthearted and sarcastic, but it appears no one picks that up. Feel free to delete this (eyeroll).
I get that you were mostly cracking a joke, but to be totally (and unfortunately) honest, there are really people out there who hold that exact belief-- and there's no way through the imperfect medium of text to tell you apart from the creepos who lock a roommate into a lease and spend all day making creepy comments about "alternate ways to pay rent" or actually harassing or actually assaulting them.
If you make a smart quip and it lands poorly, it's worthwhile to consider why. We all make jokes that don't go over well or offend people, it's just realizing that hey, that wasn't great, that makes the difference.
That said, if you do want input or celebratory noises on landing a great roommate possibly despite being attracted to them and/or any advice on making sure you're screening for good roommates to help your FIRE stash, we're all ears.
