Somewhere deep down, I'm sure he did care. You had years together, and it's going to take a while to grieve it and move on. I think a therapist told me once it was something like six months for every year you were together. Anyway, I don't think anyone here would tell you when you should be "ok" by. You are grieving a loss. Just let it happen. But if you think you're going to a deep, dark place, please seek out help.(((Hugs)))
