Ask yourself
Ask yourself whether you will have lingering guilt over keeping the money, and whether keeping it will create a kind of psychic tether to your ex--which is something you don't want, and which might be more expensive in the long run than letting the money go.
Don't underestimate the importance of really getting rid of the baggage in your life--in this case, your ex--lock, stock and barrel. Making the cleanest break possible will help with your grieving/separation process. I think, if you don't need the money in a truly big way, you should do everything in your power to sever ties--all ties. And this money is a big one.
