Husband super regretful and depressed after making hurtful comment… not sure how to handle this.

My husband made an inappropriate, hurtful comment the other day (feel free to check my post history for more details) and we had a pretty uncomfortable discussion.

I’m still uncomfortable about it, but I’ve accepted it as a mistake.

Since that night, and especially after our discussion when I explained why his comment was hurtful, he has been on a downward spiral of being depressed and saying things like “I’m a bad person”, “I don’t know why you’re with me” etc. It’s day 3 and he is still like this.

Initially I thought he was throwing a pity party, but now I’m at a loss. I don’t know what to do or say, or how to handle this. Nothing I say seems to make any difference.
