Am I in love with my best guy friend?

We are friends for so long.. I recently realized that I think I am thinking more about what I will wear when I am going to meet him.. also when he brings her girlfriend (they recently started) I don't like it, it kills my vibe. What should I do? I know what I am going through is not RIGHT and I don't know why I do and feel like this.
