Relationships problems

So I have been with my bf for nearly 3 years now. We moved in together at the start of the year. When we weren't living together we used to see each other everyday and we're excited to see each other. Now that we live together things have changed. It doesn't feel the same anymore. We're not lovey dovey anymore and I know as you are in a relationship for longer and longer you lose that anyway but we just don't really kiss or hug anymore at all. Even on weekends we will go and do our own thing. It's Like we kinda have more fun not together. Don't get me wrong I love him so much so so much but I don't know. Help me please I don't know what to do :(
