My girlfriend and I have been dating on and off for over two years. In the beginning, one thing keeping our relationship stagnant was the fact that I thought I had romantic feelings toward one of my closest female friends of five years, and had admitted this to my girlfriend. When I realized I did not have these feelings for the friend, I was ecstatic and fully committed to my girlfriend. The last eight months have been some of the greatest of my life—that is, except when this friend and I try to make plans to see one another. My girlfriend becomes abrasive and questions everything about the interaction, claiming it's a "date." She calls and texts constantly, and I have even caught her reading texts to my friend behind my back.
