What is attachment ? And why does it hurts so much when you lose it ? Attachment is basically a feeling attached to someone or being extra close to someone, the closeness and affection towards someone that makes the relationship sustain. Well if you ask me then in my words I would explain this as, See, loving someone truly and then getting the same love in return from that same person is the most amazing feeling in the world, that is what I believe. Every couple or every person want stability in their relationships. Attachment is one of the reason to sustain any relationship but at the same time attachment is a very dangerous disease. Being attached to someone means giving each other the same amount of validation, trust, love, and many other aspects. The more you are attached to someone the more it hurts because attachment ends when the partners breach trust. But I feel that this is life and we all should be prepared for everything and anything.
