8 months pregnant & my boyfriend doesn’t want me going anywhere

My boyfriend works two jobs Monday through Friday. He’s gone from 7:30 am to 9:30 pm. We live close to one another but don’t spend time together until the weekend starts. I appreciate all he is doing for me and this baby but I get very lonely and bored Monday through Friday. I don’t really have any friends so all I do is clean and take care of my dog. I told him I was going over my cousins tonight to spend a night there and he made it seem like it was a big deal. He keeps saying “Your 8 months pregnant you don’t need to go anywhere. Stay in the house if something happens to you don’t call me.” Etc. Am I doing too much by wanting to get out the house? I understand I’m pregnant but I don’t want to sit in a house all week being miserable just waiting on the weekend to come around.
