Boyfriend

Okay, I know I’m not exactly the most present blogger on tumblr, but I need advice.
My boyfriend is great. I’m absolutely certain of my feelings for him but I have issues with the way we communicate. Sometimes I feel like he isn’t paying me any attention, or he takes me for granted, or even that he’s losing feelings for me. I’d be devastated if he actually was losing interest, but it’s what I’m scared of. I want to talk to him about it. What I’m asking you guys is how should I go about it. How do I even bring up this kind of stuff? I mean, we’re both pretty inexperienced when it comes to relationships. I just need some advice. Please, I’m stressing myself out.
