What she said. The first 15 years of my marriage were the "Honeymoon Phase" ! Lol. Feeding the fire, paying attention, and putting in the effort to show your love is so important!!!

Yeah....and then you have to pay some chicks $49.95 for an additional 15. The nerve!

ahhhhhhhhh.....aren't you forgetting something? Like the credit card fee?

I also believe that it's very important to stay true to yourself. What I mean by this is not to simply become an extension of your partner. Stay who you are and who he/she fell in love with.
Don't get "joined at the hip" where neither of you does anything without the other! Your differences should be celebrated. This gives you lots to talk about and share as well as teaching you how to be supportive of your partner's activities/hobbies! This also makes the things you actually choose to do together more fun and exciting.

The "in love" feeling doesn't exist on it's own, neither does it last on it's own.

I was in a relationship for four and a half years, but I was in love with her six months before we started dating and remained in love with her for two more years after it ended. I still hold a special place in my heart for her, though, and always will.

Sexual attraction is a biological issue and generally lasts about three years long enough for the woman to get pregnant have a child get the child mobile and then the man seeks new stimulation.
