Okay, assuming you're not having a stroke or testing to see if you can sneak in any spam under the radar, my translator says you wanted to meet up with a guy and you forgot to text the date.
Then you texted again, this time adding the text, and he hasn't gotten back to you yet.
If he's not online, then he's not online (and if he's in the US, then it's one of the biggest family holidays of the year, and he is probably busy and being told to put his phone away). If it gets to be the first of December (yep, wait this long. Patience is a virtue) and he still hasn't responded, send one (and I mean JUST ONE
) reminder and then back off.
If you get confirmation, then go and have a good time.
If you don't, then don't go.
Why not go? Maybe he doesn't realize he should confirm? Maybe he was raised by wolves and has no idea that other people have lives and schedules and can't hang around waiting for him to just show up if he feels like it? Maybe he thinks RSVP means really shitty vain person
Going with no confirmation is a desperation move. It also shows that you're willing to subsume your life, your schedule, and your time to someone who doesn't have the decency to tell you they are or aren't coming.
You don't need that in your life, even if he comes off as someone who claims that everybody does it.
No, not everyone is an immature jackass.
And you don't need an immature jackass in your life.
