When most people define ‘family’ it’s usually a title reserved for people who share blood or who are related by law. In order to have long lasting relationships you have to consider each other family otherwise the people in your life will just become a girlfriend or boyfriend in your early 20’s. They will be people who will be with you when it’s easy but once you want different things you will part ways.
It’s weird, when you have it in your head that you are not family you automatically allow yourself to cut ties with that person much easier. To me family goes past blood. Family are the people you want in your regular life not just somewhere in your life. You don’t have to be related by blood or by law to be family. Your pet is your family cause it is with you everyday and you treat it like family.
If you don’t treat someone like family then they are likely to drift away. Family is your tribe. When humans were more of a tribal community they saw each other everyday. It didn’t matter who shared blood. If you don’t feel the family bond then your instincts are to go else where.
It’s just the same with blood. Someone can be your dad or brother but if they don’t treat you like family then they are just another person. People like to abuse those family titles and just as many people buy into it. You don’t treat your brother like a brother if he treats you like a 3rd class acquaintance.
We have titles for people in our lives like friend, godfather, best man but they mean nothing if you don’t treat them like family. In your head and in theory you think you can remain close with those people without ever seeing each other but in reality it’s just not true. Everything works in theory cause we can rationalize it in our heads.
