New relationship

So me and my boyfriend have been together a month. I know it hasn't been that long but I don't feel like he's letting me in. He does construction and I only see him a couple times out the week, if that. I like talking to him when we aren't together so I know how he's doing, checking in on him. But he doesn't really talk much and sometimes I feel like he's ignoring me, purposely. How do I get him to open up more and talk to me?? I'd like to feel like we're an actual couple. I have anxiety too and he knows that. What should I do??
