AIBU Friend not to bring partner

[Henrietta75]

So I have friend A who is the same age and friend B who is 15 years younger. We all get on really well but I have seen more of friend A as we used to live near each other. I moved closer to friend B but still see friend A more as friend B is very busy. Caught up with friend B recently and all good.
Friend A and me have this ‘time alone’ in the pub on a Sunday lunchtime, once a month, no kids, no partners, just us shooting the breeze talking about work and putting the world to rights.
When friend B came over I invited them to join us the upcoming Sunday but they hinted they wanted to bring their partner. I hinted back it’s our time alone but they haven’t got the message / ignored it. I have nothing against their partner but I feel put out that they’re joined at the hip and can’t be separated for a couple of hours. Am I being unreasonable thinking like this?

Why offer a future time?

Just say it clearly. This date is partner free, take it or leave it.

The 3 of us all worked together once so Friend A wouldn’t have a problem me asking B and they get on well.

She may well still be annoyed that you didn’t bother checking with her first. Especially if you’ve been too much of a wuss to make it clear that the partner isn’t invited.
Your best chance of salvaging this is to reschedule the three-person meet-up to another day as a one-off and either tell B she can’t bring her partner, or invite A’s and your own as well. Either way, leave your regular catch-up with A alone.

You were very wrong not to run this by A first, and you're being ridiculous by not being direct with B. You're an adult, be clear, FGS.

Last months meet-up we both mentioned asking B to come see how they’re doing. Not a problem.

I’ve rung B and said now it’s a girls only meet up, we’re leaving partners at home. They replied ok, I’ll let you know.

Ah so now did they did know?

You made this into more than it needed to be OP

Next time just be clear. "You are welcome to join us, it's us 3 only . "

No need to panic and imagine scenarios where friends become offended over a misunderstanding

It's be a poor friend who insisted on bringing their male partner as an odd one out, to a girls only evening of close friends and there's plenty strategies to deal with that!
