DH has a long standing female friend with whom he shares a birthday. They have been good friends for 10 yrs or so and before we got together 5 years ago always celebrated birthdays jointly.
She had been on holiday with him a couple of times as friends and after the first two years we were together got the message that her invitations to him only to go hike Kilimanjaro/visit the Galapagos (yes she is wealthy) were not that welcome.
A couple of weeks ago she texted him to arrange joint b'day drinks together, which is fine. What's not fine though is that they were in the process of arranging it and hadn't decided on a location (she will not be budged from X hipster part of London), and tonight she sends out an email to her friends - and me - inviting us to their joint b'day drinks. They had agreed a date but not location. AIBU to think this is a bit weird? Just to clarify DH has not agreed either time or location of drinks, and had not decided who to invite. The friend has included a number of 'our' friends on the invitation. Opinions v welcome... I do think she crosses the line quite a lot of the time.
