"You look like such a mom"

My husband is nonstop telling me this and at first it was great. I thought it was a compliment. Now, everytime i try to look nice or sexy, he tells me that and laughs. It's starting to really hurt me. Tonight i put my hair down (which is rare because its super long and curly) i did my makeup and put something sexy on for him. He looks at me and says "wow. You look like such a mom" and laughs. Now im sitting here crying because thats all i ever hear from him. I get it, i'm a mom. But come on. Let me feel sexy and pretty without you telling me that. He said sorry and said that he will stop saying it but it hurts that its what he thinks everytime he sees me.
