I used to live in west London and about a year ago I moved to north London because I got a new job.
I have a group of friends in west London who I've known for several years, and since I moved I've been back to west London several times for their birthdays, to see one of them after she had a baby, a hen do, a wedding. They haven't made any effort to come to anything of mine - not to my housewarming and not to my birthday - but I still tried to keep in touch via phone and email.
Yesterday I saw on social media that one of them had had a birthday night out in central London over the weekend. They were all there but I wasn't invited, even though I sent the birthday girl a message on her birthday to wish her!
AIBU to not bother with them anymore?
