Look at your numbness with curiosity but do not judge it. There are no right or wrong ways to feel after a long term relationship has ended, and six years is a long time. The one thing I can’t apply Buddhist non attachment principles to is love though. Love is attachment, and when a relationship ends we see if it was really love or ego. Love is fluid and doesn’t disappear due to circumstances, fights or being in separate places in your life. It is, as Shakespeare wrote, an ever fixed Mark. It doesn’t waiver and cannot be easily changed by new pair bonding or sexual interests. Perhaps you feel numb because you are aware enough that you know love isn’t easily transferred or ended so your non attachment wasn’t love but ego. Your emotional response is numbness and that is ok.
