It's been just over two years since a devastating breakup with an ex, and I pined for him all that time despite functionally moving on, having therapy and succeeding in life.
In the last couple of months I have finally started to let it go completely. What helped me was recontextualising what happened and what kind of man he was, and seeing it through a feminist lens. E.g. I thought we were having exciting adventurous sexual encounters, but if I look at it differently, he got off on hurting me.
Not all exes linger so long of course. What helped you?
