She once thought she needed him.
She once thought his warmth, his embrace and his kisses, his love were the things that held her up, kept her whole. She once thought he only had to love her, stay by her side, and they could figure anything out together.
But standing before him after all that, after falling and failing and almost losing herself to the belief that everything was broken beyond redemption even after she had given all she knew how to give, she realises she is no longer looking through the same eyes. She realises she doesn't fit into the space within him. She never has.
The kiss is a farewell, and a thank you. There is love there - but love has changed, and they both know it.
She turns and walks away. She is neither sad, nor happy, but she is equal parts empty and relieved; her steps are small, but they do not falter. She won't let them.
She is different now. She is also afraid, but she is certain of one thing: her place does not exist within him, or anyone else, but within herself.
She fits perfectly.
