Stayed in the whole of summer / my boyfriend won't go out with me

Basically I was really excited for school to finish so me and my boyfriend could go on actual dates and spend time with each other outside of my house. While I'm in school it's hard to do because he has work Friday and Saturday, and sees his grandparents Sunday. It's now been over a month since I left school and he still won't go anywhere with me! He always says he can't be bothered and just wants to stay in. It's so annoying, I HATE staying in all the time and I've literally not done anything for the whole summer. He knows it bothers me and makes promises that always get broken 🙄 I don't know what to do, I feel like I'm just wasting my summer.
