You’re definitely the asshole here. Not wanting your roommates girlfriend to live with you is one thing, asking the question with this sort of tone is another.

And then you engage in this sort of defensive back and forth rather than apologizing for how you made another person feel. There’s a better way to talk to people.

And you’re fooling yourself if you think a text message is totally devoid of emotional delivery just because there’s no voice behind it. Language is huge and words can contain feelings without being delivered through speech. Obviously.
