You don't want to forget this.
The way you feel right now. The way that you can't wait to see him. The way you ache when you miss him. The way you just sit and think about how happy you are. Right now.
Never take these moments for granted. This beginning stage where everything is wonderful. You are Cinderella and he is Prince Charming. Little blue birds sew your ball gown and you sing to the mice and they sing right back. There is good and bad and black and white and you are glowing sunshine.
When he forgets your birthday, remember the first time he said he loved you. When he keeps doing that annoying thing you used to think was so cute, remember dancing in your living room to Nat King Cole on the record player while dinner burned in the kitchen. When you have your first knock down, drag out fight, remember that the first present he brought you was canvases so you could paint to your hearts desire.
Now some say that this right here isn't true love. "True love" is not getting divorce after he goes to Vegas with his friends on your anniversary. It's holding her hair back while she puking pepperoni pizza and beer. It's getting up at 4am to feed the baby, even though you have to go to work in 2 hours, so he can sleep a little bit longer. I agree fully, but this too is love.
This shiny, happy moment is gone before you know it. There is more to come, but just don't forget this. It can keep you through the lean times and move you through. Don't ever forget.
