Can't remember what I said

Hi, my husband has recently told me that I am person who make hurtful comments and I ask him to give me an example when it really happened - he told me that I said ... during a conversation with my family members. I don't remember at all and even the conversation. This has never happen to and seems like my husband is lying and it made me more angry. I ask him for the details and when the conversation happened exactly and he just became angry and told me that I am crazy.

I am not sure if I am getting crazier like what he said or my husband just lying to prove his point that I am not a sensitive person.

What should I do?
