I agree with bring it out on the table. I would do this in a semi public setting, like in a restaurant that wat an outburst can be avoided.
I would calmly ask why he feels it necessary to disrespect me in the manner that he does and how can it change. You need to stop the disrespect and belittling toward you before it become overt.
Does he love you? Do you love him? Try to find out why he acts this way toward you. Does he have friends that are this way toward their spouses? There is a reason for his behavior and you need to find it out now before it develops into a nasty situation and becomes mentally or physically abusive.

Good luck to you,
