Speaking as someone whose divorce was final about ten months ago: There is a lot to be said for reducing the emotional overhang of the past relationship, and doing that is worth spending some money. You might be buying a lot of serenity for that cash. As to what else you
buy, that is less important.
However, I would also recommend not making any major decisions until the dust has settled. It will take time for that to happen, but it is easy to make a decision that appears to be for perfectly-logical-reason-X, but really was "I want to not feel this way right now." For example, I did not make any money decisions until after we had the signed separation agreement. That took us about a year into the process, and even that might have been a little too soon. I don't really regret any of those decisions, but I am not sure I would make them the same way if I had waited another year.
And that advice is even before this part:
This is a TERRIBLE TIME to make long-term
DVC purchasing decisions. You are on vacation, having the time of your life---during a period where "everyday life" is a lot less pleasant than it normally is---and DVC is offering you the chance to bottle that vacation magic for decades to come "at today's prices."
