What would you do if someone sent you a sexual harassment message in the middle of the night?

If I were you, I would do what you are doing now, just let my husband know. Although your husband said he was joking, I believe your husband will do something relatively. It's just that he hasn't thought of a good speech yet, or he doesn't want you to be too unhappy and worried. He'll handle it himself. After all, he is a colleague in the unit, and his husband loves you, so he said so. Think about it.
