Is my husband trying to leave me?

I’m 8 months pregnant and over the course of the last three weeks, my husband keeps telling me how immature I am, how he has grown and I haven’t, and is constantly trying to pick fights with me over EVERYTHING under the sun. I feel very hurt and blindsided - I’m constantly walking on eggshells because I’m worried he’s going to blow up at me with his cruel words (e.g., I can’t stand to be around you… why don’t you leave so I can have some peace… etc.). When I tell him how his behavior makes me feel, he tells me “I react to the way act, so that’s on you.” We have a 2.5 year old and I’m due any day now. What are your thoughts?
