Heartbroken

My husband told me he loves his family (his mom dad and siblings) more than me during an argument 3 months ago. His family hates my guts especially his mom and tries to make him divorce me and he knows it. He said it during an argument and said he said it out of anger. I’m the mother of his children. I have done everything for this man except die for him. When he had nothing I stuck by him. I stuck by him no matter what his family put me through. I can’t get it out of my head it bothers me so much and makes me cry still. We have a 1 year old and I’m pregnant with his second child. He said it to me while I was pregnant. I’m almost due with this baby. My heart is shattered. Idk what to do or how to get over it.
