I've been friends with someone for 12 years, and we've always had a great relationship. The issue is her husband, who I feel is very controlling, although she either doesn't recognise it or chooses not to see it.
Whenever we meet for lunch or drinks, he'll use a phone tracking app to see where she is and then unexpectedly show up. I know plenty of families use location-sharing apps for safety, but it doesn't seem normal to me that he regularly turns up during our time together.
As soon as he arrives, the atmosphere completely changes. What was a relaxed, fun catch-up suddenly becomes tense, and we end up feeling obliged to include him in the conversation. It's awkward, and it spoils the time we had planned together.
This has happened on several occasions now, and it's starting to affect our friendship. I've tried mentioning it to her, but she doesn't think there's anything wrong with the situation. I'm not sure what to do next.
