Help!!

I have a boyfriend who I love being with, but he's always playing baseball or always talking about it, our conversations are always so depressing no matter how much I try to lighten the mood and change the topic to something else then he just gives me simple replies, I always have to start the conversations. Like its always me telling him good morning and asking him how he slept and stuff and I told him there was no one better but him, and I'm starting to feel like there is, I have a really good guy friend who I've had a crush on since my first day of sophomore year, and he likes me and he texts me every day and I think he's amazing, he really shows he cares, and he like rock music like I do, and I can't go to sleep without thinking about him. I don't want to hurt my boyfriend but idk what to do. Does anyone know??
