If you talk with him, maybe it's best to have no expectations. I just broke up with a man but we had only been together for a year. Even so, I sense a grieving process is going on in me. Grieving the loss of relationships is important. I've tried to deny the break up had any big impact on me. But then the stress took over and I started blacking out and throwing up. So maybe denial doesn't work. I don't think there's anything with just crying and crying until the tears finally dry up. Can't predict how long that will take. But it is, for me, a comfort.
