Relationship issues

So my boyfriend is hanging out with his friends 24/7 and never makes time for just "us". If he takes me to dinner, he's taking at least one of his friends with us. I stay home all day every day, pregnant and bored (I live big island Hawai'i so there's nothing to do but go to the beach) & it's not like I can just call up my friends because they have jobs and a life and can't just cater to my every need! And plus when he comes home, he's too tired to do anything with me, even a simple conversation is too much to ask for. Sorry for the life story but I needed to vent and advice would be lovely 👍
