In my opinion you are not overreacting! He is your husband and is supposed to make you feel better about yourself, not worse. And the fact that he does not take you seriously when you tell him you are offended is even worse. I would say that making fun of icing color is kind of a big thing, at least in the context. You went to a lot of trouble to make a nice birthday cake for your son and he then puts you down? The other concern in all of this is that your son (and other kids if you have them) sees his father treating you this way. That is his male role model, and that's not a good thing to teach him. Is it possible to have a bigger sit down where you talk about it and tell him he needs to change his behavior towards you? Thanks for posting this and I hope you will let us know how it is going.
