For me, it's complicated to define.
It means that I trust her with me- with my littles, with my memories, with my secrets. That I am letting her connect to the most vulnerable parts of me and that I can very clearly feel that connection. I picture it like a flow of electricity connecting us together and pulling us close to eachother.
It's this feeling of - hold me and please don't let me go, it would hurt too much.
Here's my heart, so fragile and barely together, please don't break it.
I need you to remain a part of my life, somehow and in some way, and I wish I could be a part of your life, somehow and in some way.
A safe bond, one I never got through the mother/daughter relationship. An unconditional relationship. A relationship and love like no other, really.
