It seems you have joined/are joining the ranks of people ending relationships. What can I say that you don't already know? There are times when words are useless, no matter how well-meaning they are.
We try to manage loss and staunch grief, but perhaps these emotions are based on false assumptions. Our lovers will be there indefinitely, and that is what happiness is based on. When in fact, most of them leave, sooner or later.
So what is there to hope about? And I'm not sure what the answer is. Some people have resorted to living in a series of authentic moments, rather than hope for an everlasting love.
But deep down, everyone wants love, the kind that stretches beyond your horizon. The kind than transcends, not only space and time, but even our own mortality, even death.
But we don't know if we will have that, or when, or with who. And as we grow older, we start to surrender to the idea that maybe some aren't meant for that kind of love. People who have lost two husbands, and a parent, or a child, have a deeper understanding and acceptance of the mysteries of life. But you aren't there yet. I'm not there yet. You can't expect to be. We're too young, not yet close to philosophical. You want him to change, to love you again, and we have to hope that happens. And also … also prepare as much as we can for the possibility that he might not.
We talk to our friends, read books, in our search to understand what happened, and how to change things. But there are things books don't say. There are some terrible times when knowledge isn't power, when being sane or intelligent won't save you. You are standing in the middle of the night in an arctic sea on a flaming ship that's exploded. Maybe I can help. We are going to try. But perhaps all I can do in this moment is make you feel slightly less alone on a burning deck.
