I think we all depend on that “closure” to get out of things or we feel that closure will help us heal and will make us feel better. But, in my experience, closure has never helped. Because we always end up craving more of it. That “last” meeting or "last"talk is never enough and we always feel that something more is required to get "closure"We want a last coffee, last kiss, last talk, last dinner, last goodbye. It never ends. It is always better to try and heal ourselves without depending on that other person to help us through it or depending on them. Probably talk to others about it. It’s great you shared your problem here.
