I recently experienced a different issue that you with the same outcome.
At the end of the day you have to decide whether you have overreacted, and whether you are happy with the outcome, whether the issue is in your head, or thiers.
In my case I’m confident that 50% of the issues were in my head, but even with such a self admission I decided I didn’t want to socialise with a group I was uncomfortable with as they weren’t going to change thier behviours to suit me – why would they. It nvolved biking and that time is important to me.
Like you, I may have overreacted but I’m more comfortable without them that I am with them.
I haven’t read the above but in my mind I think you should discuss the issue, admit you reacted strongly and explain the importance of your pager due to your role. If they can’t respect that, walk away and find some new mates, but dont beat yourself up over it.
