Agree with what dans saying here... those friends don't sound very loyal. People change and often change in different directions. Find out where you gravitate your time and effort to. Find other people who do the same. There you can start to build a new circle of friends who share similar interests or values.

You bring up some good points and I agree with curating friends but I guess what i'm thinking is this is more of a societal problem - where people don't value friendships like they use too probably due to many reasons like - the system we live in is high time preference - people work too much - social media and netflix while curating friends can help fix this to a degree maybe...... in my experience it seems rather hopeless as people rather relationships that are via text and superficial. maybe because people are mentally drained from their stressful lives? anyhow, i guess maybe what im wondering is - is this common where your at?
