DH has a long standing friendship with an ex colleague (H). Both academics who get together to cogitate on the latest research and share tips on dodgy cardigans. Occasionally we get together as couples. H's partner (S) is nice enough but we've not really hit it off as friends, just acquaintances really.
Last year at ours S met a new friend of mine (B). They hit it off straight away as they're from the same country. After this we received more invites for both us which were also extended to B. At first I didn't mind but S and B were increasingly slipping into their native language and I felt a bit surplus to requirements.
The last couple of times I've been left out completely, not even invited. If they were pursuing their own friendship separately that'd be fine, but they're not. It's like B is being treated as DH's +1 because S likes her more. DH agreed it was rude and inappropriate so started turning down all invites and just having his regular get together with H at their sports club.
All would be fine except he's gone today and S and B have gatecrashed as S thought it'd be nice if they could all have lunch together because it's been a while. They're also really keen to have a go at the sport so are talking about making it a regular thing.
Would this piss you off?
