There’s no such thing as “busy”.
It’s all about priorities.
If someone is saying they are busy.
It means you are not a priority.
Before you prioritize someone.
Make sure it’s mutual.
You should only prioritize people.
Who prioritizes you.
You should only care about people.
Who cares about you.
When someone doesn’t care.
You should stop caring too.
It’s called self respect and self love.
Your self respect and self love should always be stronger than your feelings.
