My girlfriend’s best friend loves to visit our apartment whenever my girlfriend was away. I had to tell my girlfriend about it, but she never takes it serious, until I got her pregnant. Me: “Hey, isn’t your best friend coming over a little too often?” Girlfriend: “Why? She’s my best friend. What’s wrong with her visiting?” Me: “Nothing. I’m just saying she’s always here whenever you’re not around.” Girlfriend: “Maybe she likes your company. Don’t make it weird.” One afternoon, her friend arrived with food. Friend: “I brought you something to eat. I figured you might not have cooked.” Me: “You didn’t have to do that.” Friend: “I know. I wanted to.” She even remembered my birthday when my own girlfriend nearly forgot. Me: “Wait, you actually remembered my birthday?” Friend: “Of course. Do you think I don’t pay attention to you?” I laughed, assuming she was just being a thoughtful friend. But she kept doing little things that made me wonder. One evening, I finally asked her directly. Me: “Can I ask you something?” Friend: “Go ahead.” Me: “Why do you always come here whenever my girlfriend is away?” She stared at me for a moment. Friend: “Am I not allowed to visit my best friend’s apartment?” Me: “You are. But sometimes it feels like you plan your visits around when she’s not here.” Friend: “Maybe you’re thinking too much.” She smiled and changed the subject. I let it go because she never openly flirted with me, and I didn’t want to create problems between the two of them. Then my girlfriend told me she would be away for a week. Girlfriend: “My friend will come around to check on you while I’m gone.” Me: “Check on me? I’m not a child.” Girlfriend: “Please. She’s helping me out. Just be nice to her.” I agreed. I had no idea that decision would change all three of our lives.
