Is there there a word to describe fall out between friends without any argument or quarrel? [closed]

If two people who used to be friends just stopped being friends with out any reason? Like they used to talk before but now they slowly stopped talking or contacting each other?


Solution 1:

The friends lost touch with each other:

to stop communicating with each other : to no longer know what is happening in each other's lives

They were friends in college, but then they moved to different cities and lost touch.
