I'm talking about people in your life that you frequentely see and are on good terms with, but you're not close enough to actually have a real talk about something with more importance. So what do you say or more importantly feel when they happily tell you about their bluepill new relationship or sth similar.

I'm not really interested in faking a whole conversation about how happy I'm for them when in reality I feel like this fool is openly running into a knife. So often I'm quite distant, end it with an "I'm glad you're happy" and realize I'm looking down on them a lot. I don't know if that's really healthy.

What do you do in situations like that?
