I don't want to waste my time (T . T)

My boyfriend and I have been together for almost a year and for the first few months things were amazing and I couldn't have been happier. But now he barely even acknowleges me and we both know it's mostly a communication thing but it feels like I'm the only one trying to fix it. I care about him so much and he's very important to me.... But I don't want to waste my time if the effert is only going to be one sided.. Ladies, I need some advice please! I'd do anything to keep us together but I know there's a point where you can't really do much more :(
