Your phrasing in that post reads like boilerplate neutered corporate-speak, of the kind you'd get from some HR parasite instead of another fellow co-worker who might actually give half a shit about your misfortune. To start, describing their being fired as "parting ways" would be flat out insulting enough to toss the whole thing into the trash folder.

Also, "Don’t feel like you have continue the conversation if they respond. You can if you want, but don’t feel obligated."

Then what's the point of saying anything if it's just a meaningless single token of HR-speak sludge? better to not even write in the first place.
