But there's a lot to be said for a completely alone adventure. I'm in a wonderful, 5 1/2 year relationship and me and my SO are practically joined at the hip but I still embrace that freedom of no compromises, no having to discuss when you'll stop or where you'll eat.
For my 40th birthday, I took a spontaneous road trip - I had 3 days off from work and I brought my suitcase to work with me on Tuesday and left immediately upon getting out. Just drove with no destination in mind. I ended up standing on the rim of the Grand Canyon on the morning of my birthday (Thursday) and since my b'day is in January, there was almost no one there and a beautiful carpet of snow. It was the most magnificent sight I ever saw and the best birthday I ever had.
That night, I had a nice dinner in an Italian restaurant in Price, Arizona, drank a bottle of wine, had a slice of cheesecake and took a long, hot bath in my hotel room. I drove home and arrived in time for work on Saturday - didn't even go home beforehand.
Being alone gives you so much insight into who you are, what you like, what you think and feel. I tend to take it to extremes (I decided one morning to move from Vermont to California and I was driving by that afternoon - I also hitchhiked across the US a couple of times) but I firmly believe alone time makes time spent with a loved one even better.
Here are a couple of shots from my 40th -
