@JML,
Yes. Good heavens, if something like this makes you upset, then your relationship will never survive the arguments/disagreements that most couples have at one time or another. He might as well walk away now.
Maybe he needs to simply stop trying to complement you. Would that be ok? Maybe you are just too sensitive to your age and the age difference. I think you need to let him know that you overreacted and tell him you are a bit sensitive about your age. Then, if he is smart and loves you, he will avoid age related complements. lol
