I still don’t think I fully understand the context of the question. Of continuing what? Life? A specific relationship? Something else?

I consider myself an “optimistic nihilist” in that I believe there is no inherent meaning or purpose to life—but that can be viewed as the ultimate liberty. We can do whatever the fleck we DECIDE we should do with our lives. Everyone has their own answer, if “life” is what you were referring to. Some live for God, some live for some other purpose they believe in, some may have the other form of nihilism and struggle with seeing the point of it all (maybe that’s what you’re doing?)

If you mean within a relationship, then, if there was a one and done purpose I don’t really think the relationship was as strong as it could’ve been. Ideally relationships are mutual. This doesn’t necessarily mean equal on each part, but each part should be happy with what they give and what they get. Not all relationships last forever (thank God!), but I think when there is more meaning to them, more giving and getting, more breadth, they at least seem to last as long as they need to (once the acceptance part of grief has hit if it ends).
