AIO: My bf left me at the airport by myself after he made us late for the flight but miraculously made it.

Me and my bf were in Seattle for Thunderdome and we’re from ATL. He wanted to save money on the ride to the airport and booked us a Lyft to a random hotel so we could catch their shuttle instead of having to take a direct ride to the airport which saved him $30. We get to the airport and we’re cutting it REALLY close. I’m in a separate security line and his clears it about 3-4 mins before me. He stated that he was going to go the the gate and try to make sure we both make it on. I get to the gate 4 mins later and the door is closed and he’s nowhere to be found. At that moment I realized I’m stuck in Seattle by myself and that he made it on the plane without me. I checked my texts and from a minute prior he sent me the message “run”. I had already been running but missed the flight by 1 minute. The flight left at 4:05pm and the next one out isnt until 11:05pm. I won’t get back until 6:45am and have to work at 8am. He doesn’t have to be to work until 12 pm. Based on my personality, I wouldn’t have gotten on the plane unless I was sure he’d be on there with me. Now I’m stuck in Seattle for 6+ hours by myself. It feels like he was being selfish but maybe I’m looking at it the wrong way. He called while the plane was pulling off to give his side of the story and said the gate agent told him I would be able to make it if I got there in the next 2 mins but he didn’t even stay to make sure I made it on the flight. My feelings are hurt and I’m genuinely questioning if I want to stay with him after this.
