Help?

Lately my bf of three years has been checking out other women. At work I don't get to talk to him for 6 hours on end and experiencing early pregnancy it's hard. I know my hormones are changing but he doesn't understand nor does he know I'm pregnant yet. I love him but he's been emotionally abusive lately and I don't know how much more I can take. I really just needed to vent but I'm honestly tired. What should I do??
