I’m dating a beautiful, caring woman whom I had felt madly in love with, and we’ve been together for nearly six months. We’ve said “I love you,” but I’ve been clear about taking it slow. A few weeks ago, I met an acquaintance of my girlfriend (they’re not close friends) and was absolutely smitten with her out of the blue. We only talked for several minutes, and I firmly put her out of my mind, but that only lasted so long. I looked her up on Facebook and discovered that we had the same college major and are both avid runners. When we first spoke, I felt that sparks were flying beneath the surface, though I stayed very formal the entire time. Since then I haven’t felt as attracted to my current girlfriend, and I’ve been wishing I was single so I could ask out this other woman. Am I leading my girlfriend on by continuing to stay with her, even though I’m thinking about this other woman? Is it absurd to consider ending this previously solid relationship for the hope that, once I’m single, I’ll be able to ask out this other woman and see where things go?
