Facebook Enables Insecurity

Girls like to over-analyze. So do bloggers. Therefore, I can feel justified in falling into multiple stereotypes as I write the following.

Today, I noticed that despite the fact that my boyfriend and I currently live 4 hours away from each other and only have the chance to get together once a week at best, approximately 50% of the pictures tagged of me on facebook from this past year have him in it. That’s grossly disproportional to the amount of time that I spend with him.
Why so many pictures of us together?
I recently read an article which reported on a study that found that people are happier with their relationship when they see pictures of them with their significant other. So perhaps that’s it.
Another thought hit me tonight. I am going kayaking with him tommorow. While thinking about what to pack, I debated bringing a camera. Pros-kayaking pics are awesome. Cons-digital cameras are expensive to replace if damaged by water. Clearly the cons outweighed the pros on this. But I REALLY wanted to bring it. Why?? I have gone on a number of fun outings this summer with friends (strawberry picking, fourth of july fireworks, outdoor movie on the waterfront) where I felt no need to take pictures. But for some reason, outings with my boyfriend seem to necessitate picture taking.
Furthermore, what is my purpose in taking the pictures? Are they for me or for my friends? I certainly feel more of a push to publish my boyfriend pictures online than my friend pictures.
Could it be that I need to project how cute of a couple we are to the world? Am I that insecure with our relationship, that I need other people to see how happy we are? Do I need a reminder that my relationship is a happy one? Why isn’t the knowledge that I did those things enough?
Am I so insecure in my relationship that I have to validate it by posting tons of pictures of me and my boyfriend? Have I really become THAT girl?
