So I (31M) am part of a friend group for around 13 years, we met when I joined a tabletop rpg club in my city. And we've friends since, when the club close down due to covid, we continued to play online then at the DM's (33M) house after lockdown ended. He and Bob (45M) are the two I'm the closest with.
Recently though they started to meet without me. I heard them talk twice about board games sessions, past or planned, I wasn't invited to and I learned Thursday that they celebrated new year's eve without inviting me.
New year's eve has always been a big thing while the club was running and, we as a smaller grouo have tried to maintain this tradition after the club closed.
Those 3 meetings that I know of took place at Bob' house and I know he's entitled to invite, or not, whoever he wants and I'm not owed an invitation, but he's been one of my closest friend for 13 years and just a few months ago, I was invited to his wedding so it does hurt a lot to be left out like that without an explanation.
We had no fight, fall out or argument that could explain and neither him nor DM are the kind of people to hide their resentment so I assume they'd tell me if they had a problem with me.
How can I talk to them about it ? How can I determine if its worth salvaging. I value these friendships a lot so I'd rather try to repair the relationships if possible. And, at the very least, have an explanation.
