Baby Daddy’s accident

I’m confused. I went to the hospital to find my husband after 4 days of being MIA. I’m pregnant with his child and feel like i’m the one that needs to be by his side. The day I went there was a woman visiting him. Now he says that I can’t come see him in the hospital. I feel sick to my stomach because of his condition but also feel like he doesn’t want me by his side because he already has another woman or women by his side. I am super heartbroken and confused! why won’t he let me visit him??
