4 weeks ago I had ‘significant’ birthday. Had friends over, it was great fun. Organised by DW. Followed by a family holiday. An old friend, female, that we see a few times a year and both our families get along well, invited me for a belated dinner as birthday thing. She is an ex, from 30 years ago; To me this is more or less lost is the mists of time. DW says it is weird and that she ought to come too. Which is fine, OF and DW are friends. But it doesn’t seem weird to me, just sweet/thoughtful. I’m slightly concerned that DW sees it as inappropriate. Can you lot put me or DW in our our place ?!
