You would have liked to be included, but you weren't and you let him know it bothered you. This seems like a normal reaction, since in the past he's been excited to share ideas and plans leading up to it and this time it was just a statement of this is happening.

It doesn't seem like you're upset about the tattoo, just the fact you weren't included in the way you were accustomed to. And frankly I would be hurt by that too.

If he doesn't get how that would upset you, there may be more to talk about as to how you communicate within your relationship.
