Long term relationship

Let me just say that there’s nothing wrong with our relationship, I just want some tips. My boyfriend and I have been together for just over a year, but things feel a bit different. Of course they would because we have been together for a long time. What can we do to keep our relationship ‘fresh’ (I don’t know how to describe it lol). We’re both still young so don’t really have a lot of money and we live in a very rural area so there’s not a lot of date options. All we ever do is just lie around inside and it’s getting a bit boring. I want to become closer to my boyfriend.
