For context, I'm with my partner for last 18 months. We are both divorced with kids, see one another every weekend. Both early fifties.
I have worked with same colleagues for last 15+ years. We are very close friends.a small circle.
He has left his job an hour away six months ago to move to another job. He hasn't met ex colleagues since but a work night out will be happening next week for them and they've invited him back . I've only met the three colleagues with whom he became friendly with, once.
He will Travel to go to this night out And is excited to see them.All male.
A few weeks ago I had a work night out with my colleagues/ friends and invited my bf to come up afterwards to meet them briefly towards the end of the night , have a few drinks and stay in hotel. He came and we had great fun.
Now these are very good friends of mine outside of work whereas his friends/ colleagues are people he worked with and to hours but little contact since except for the odd message or chat.
He hasn't asked me to come and meet him afterwards and stay.
AIBU to feel a bit off about this?
