I (22F) have been dating my boyfriend (24M) for almost a year now. He's a great guy most of the time, but sometimes he has this "nothing is ever that serious" attitude that drives me crazy.

We planned a vacation together for months — my first time leaving the country! I was beyond excited. I triple-checked all our plans, flights, hotels, passports, etc. He kept teasing me about how "uptight" I was being, but I just brushed it off.

The day of our flight, we were running a little behind because he insisted we stop for coffee "real quick", even though I said multiple times we were already cutting it close. He laughed and said, "Flights never leave on time anyway."

By the time we got to the airport, it was pure chaos. Security lines were insane. I begged him to hurry, but he kept joking around, stopping to look at snacks, and even taking selfies in the terminal. I was furious but trying to keep it together.

When we finally got to our gate, the doors had JUST closed. We missed boarding by literally five minutes.

I broke down crying right there. He tried to hug me and said, "Babe, relax, we'll get on the next one." — like it was no big deal. Except the next flight was sold out, and the earliest we could fly would have been two days later. Not to mention, we would lose our hotel reservation.

I was so upset I told him I needed a minute and just... left. I called an Uber, went back to my place, and didn’t talk to him for the rest of the day.

Now he’s blowing up my phone saying I abandoned him at the airport and ruined our trip by “overreacting.” He says it’s my fault for being so "high-strung" and that if I had "just relaxed," we could've still had fun.

Part of me feels guilty for leaving him there alone... but also??? I told him a million times we were late. I feel like he just didn’t take anything seriously until it was too late.

So, AITA for walking out after we missed our flight?
