Uh... that's not the point? If this was a question of who's right or wrong, then in case she actually is running with the kid, we would have to ask HIM to not say "I fucked up by accidentally texting her" (let alone me saying he fucked up), because who cares what she feels about the text if she's really doing it?

"Fucking up" in this context has nothing to do with right or wrong, it only concerns how smoothly a certain isolated situation could've gone instead of how it did, and to me, it would've been better if he just told her straight, than to say it accidentally. He's not wrong, he's a victim, and if she in fact is leaving the country, then well, yeah, she is wrong.
