The company I work for is fully remote and my colleagues are spread across Europe. In March they were planning a trip to Rome and asked me if I wanted to come. I said yes. Some of us were meant to sleep at one of our colleague's place the rest was getting an Airbnb. The colleague offered me to stay at his place. Then I moved apartment and was busy with the move. So I told the group that I might not be able to make it. I then changed my mind and said I would come, but return back home earlier. Eventually, I decided the trip was getting too expensive, so I decided not to go. I let my colleague know who lives in the same town as I do. I never messaged the rest of the group (yes I feel bad about it).
Now they sent a message in the group talking about going to Lisbon in November. I'd be keen to join, but I'm not sure if it's appropriate to ask, after having ghosted them last time.
What do you guys think?
