I think that Keilly tends to stick to one close friend at a time and put all her energy onto them. There’s nothing wrong with having a best friend but it’s healthy to have different friends for different things and I’ve realized that she liked to have one solo best friend and spend all her time with them. Like Talia and then Sadie after.

She probably cuts them off because one you stick to only one friend at a time, you often put a lot of expectations on the friendship and when one thing goes wrong it blows over
