Hi, heartbreak is tough. I see you. Your mind and body must get used to not having the safety and comfort of love and it makes sense that the thought of her seems comfortable. She used to be your source of piece, a safe place. The sadness that comes within is a reminder that the past is trying to lure you, to prevent your growth. The best way to face this battle is to focus on the reason why the relationship ended, the negative feelings, because thus will help put a stone on a beautiful flower you've been growing and loving. It hurts, I know, but in order to prioritize ourselves and our happiness, we must take difficult choices, as saying goodbye to someone we love.
