Worst fight with spouse?

Hi, just wondering what the worst fight you have ever had with your spouse was about and how long did it take to resolve? Im 7 months pregnant and my husband and i got into a fight a month ago and there has been no progress in making things better. He has told me several times he no longer sees our marriage being the same. The reason he is mad is because when we were arguing i told him and his mom to get out of the house. He feels i disrespected him and his mom. Ive apologized numerous times to both.
