If he did that by coincidence, it's eye rolling ironic. He may have been so blind to you and hardly even heard you say or noticed you were quitting smoking. You are assuming he had the ability to empathize that you were quitting smoking, so would be irritable, and he would have the tact to wait a while to give you stress.

My husband probably wouldn't have put all that thought together about me, either. Selfish? IDK, just not aware or empathic IMHO.

If he did it on purpose, knowing you were quitting, one would think he was trying to sabotage your success.
