I think you totally can respond no, and if they ever ask you can say “oh I’m so sorry I have a commitment for that day that I just can’t reschedule” and apologize. It sounds nice that they invited you, but also it doesn’t seem like you were close enough that you’d miss/regret not going. 

...everyone here telling me to go to the concert when I really just want an excuse to not have to see it and go to a wedding, lol. 

you don't follow this person on social media? you're doing them a favor by not going to their wedding. go to the concert. No brainer! 

Go to the concert. Your SO is more important than a former bestie. 

if you wouldn't be upset in the slightest that this person didn't attend your wedding to go to a concert, then I think go to the concert

Also, I should note that I have only spoken to them during those 1-2 times after college that we hung out — I don't even think we follow each other on social media. 

Which one will give you more pleasure? I'm guessing a concert, since you will get to rock out to your fave music live. Weddings are overrated, especially if you won't have a squad there to party with. Also, you spent your hard earned money on those tickets, so gotta use them!

Good luck, no matter what, follow your heart. 

Wow, that is so annoying though, like of course it had to be on the same date. I think you should go to the concert because it has been like literally years in the making.

Is there a world where you go to the wedding, SO goes to the concert?

If not, go to the concert and send a nice gift + note. It's her big day. She'll be to worried about other stuff to be hurt by one person's decline, especially if you send your regrets.

Okay, this seems like an obvious choice at face value, but let me set this up a bit. 

Back in 2019, I got my SO two tickets to a concert as a Christmas gift. See, this was a generous gift, given a) I hate concerts, and b) I am not at all a fan of this particular artist, but he is. 

Because of COVID, the concert got pushed back to 2021... and then pushed back to 2022. So it has now become a long-awaited event with a lot of excitement between it. 

That's all well and good, until an old college friend sent an invitation for her wedding, the same night as the concert. (Literally, the only night I have a prior commitment in 2022.) I am not sure what to do, and need advice!

-I was very close with this person back in college, but probably have only hung out with them 1-2 times since (mostly because we live in different cities)

-This is not the type of person to invite someone to a wedding just to get a gift — I do think it's a friendly gesture

-My SO has met this friend probably once, but has no strong connection to them

-Both events are in different states (and a different state than I'm currently in), so I cannot accomplish both in one night

-The concert tickets were reasonably pricey, but nothing that would keep me from paying my bills 

Should I go to an old friend's wedding or a concert?
