He got stoned and fell asleep on our last day together and I’m fuming, AIO?

I (36nb) am in a long distance relationship with my partner (43m) since November. We love each other very much and have spent ~25-30% of our time together since we met. He cannot travel to where I live because of papers (for now - he’s waiting for the one document that will allow him to travel, should be another 3 months or so) … so, for now, I’ve been the one flying back and forth.

I’ve been on a specific job since early February and only managed to get away for just these last 3 days so I flew over to see him. We won’t see each other again for almost a month after this. I’m leaving for the airport at 4am, it’s now 9.45pm, we had plans (not “outside” plans, just… you know, dinner, movie, s*x), and he’s smoked a big spliff and is now deeply asleep. At 9.45pm! I am sat here watching him snore and I’m f***ing raging. I have zero judgement about him being a stoner (I don’t smoke but most of my friends do). I don’t want to be mad, because I love him so much, but surely it’s not that hard to stay awake, given the context? Is it? AIO and if so can someone talk some sense into me please because I’m so, so mad right now.

TLDR: long distance boyfriend that I don’t get to spend lots of time with, falls asleep at 10pm

on the night before I leave for a month, after spending the day promising we would do X, Y and Z when we got home. I’m fuming. AIO?
