At least once a week, make sure you spend a chunk of quality time together where you do not talk about anything related to your wedding. Do the things you love to do, and make an effort to talk about non-wedding topics. This is good practice for remembering all of the other things that are going on in your lives that have nothing to do with your wedding. By staying engaged (pun intended) in topics of interest other than your wedding, you are less likely to end up boring your friends by becoming consumed by the party planning process. More importantly, weekly planning breaks will keep you in touch with the reasons you are marrying one another in the first place!
