People change anon, sometimes you connect with people and feel a drive to hang in them, sometimes you fall apart not out of hate, just out of developing different goal in life. Doesn't mean you hate them nor that it was premeditated, people usually need a reason to stick together in the first place, even when they frequent the same spaces. They may stop hanging as much eventually when they want to play different games but that doesn't mean the time they're currently spending together is non genuine, nor past relations for that matter. Friends are fluid like water and nobody with a healthy social frame can force themselves or other to stick in the same place forever.
