have lived with my gf since 2002, got married in 2004... Free time is a must. Love is great, but you still need to be yourself. The honeymoon period will wear off, find things to do togethe rin common i.e tennis, movies, biking, poker, bills games whatever... Communication is huge, try to prevent grudges from forming, communicate about the sheet that bothers one another. Most important is compromise compromise compromise. In addition, its not a matter of whether you fight, but how you fight. Keep that in mind... Fighting, disagreements are normal, but the way in which you argue separates a healthy relationship from an unhealthy one. Good luck, and enjoy... Sex eventually becomes less frequent, as the challenge is no longer there
