Like, after they get in a new relationship, and they only have time for you at lunch, or on Tuesday night, or when their new boyfriend is not available… no longer any availability during the ‘prime’ entertainment times like Friday evening etc.
for context, I fully expect that they will have less time available, which is fair enough. but not to even make any effort to pretend that you still are important and worthy of more than a coffee at a time of their convenience? It just feels shite and doesn’t inspire much confidence that they actually value you as a friend now that they have found their ‘other half’ (intentionally in inverted commas!)
