Because loss is an inevitable part of all relationships. None of them will ever last forever. Many of us accept that, not cynically, not guardedly, just naturally as the way of life. So we may feel loss and sadness, even grieve, but we don't necessarily equate the grief we experience as suffering, or even if we do feel we suffer, it is temporary and we pick up and move on if we allow ourselves that natural process of grief. You may just need more time, Budfox. That's okay and it can hurt like heck when we encounter loss in life, but hopefully you will be able to experience your feelings and eventually heal and move forward.
