I don't feel like there's 50/50 work in my relationship anymore?

I know my boyfriend loves me and I love him too, but I feel like I'm always pulling the weight in the relationship. We've been together for about4 years and needless to say it's been an emotional (even physical) struggle. If it was to end, I'd take me a while to recover only cause I've given so much, maybe too much, into this. But he never makes any attempts. He's off in la la land, living his own life, perfectly content in keeping me in the dark until I have to always speak up. And to him, it's small things that shouldn't get me upset or mad. And he's right, they are small things. But they eventually ALL add up to make this big thing that kinda gets under the skin. I can't shake it. This...anger, hurt and frustration. I try so hard, so can enjoy being with him and be happy. I've worked SO damn hard for this and to keeping him, and I feel like he never see's all the hard work I put into this relationship. He's so oblivious, he never see's me it feels, unless I'm screaming in his face. And I know he knows when I'm upset, but he's too scared to ask me, and it hurts when he ignores how I feel. I feel ignored, over looked, neglected and like I'm wasting my time! I feel like someone else would appreciate me better. I have guy friends that truly care for me, and would do anything for me, but I can't see anyone but my bf. He's the only one I want, so I'd be pissed if it fell apart again because my bf was being a stupid idiot lol. I guess I just wish he saw what everyone else saw in me, this funny amazing girl. I'm not cocky. In fact I've been tearing myself down till recently, because I know I'm a cool chick and I know I'm good looking. When I'm hanging with my bf he's all over me, telling me how much he's in love with me, calls me beautiful all the time. Whenever I text him he calls me all these pet names like baby and honey and sweety (his fav) and says I love you at least 3 times. And before I'd be like aww I love you too! But I'm so aggravated with him lately I don't even say it back half the time. Yesterday I got so annoyed I asked him what he had for breakfast? Instant dick? I feel like I'm over here, in the shadows miserable, and he's over there all happy and whatever. It's not fair. I put more effort, time and my heart into this and he's still happier then me! What am I doing wrong? What should I do?! I love him so much, and he's been in love with me since the 6th grade (we're seniors in HS now) so I know he loves me, and I know this sounds SO wrong but the sex is great, so add those 2 things and it makes it impossible to think clearly and leave. I dont wanna leave him. I'd be SO angry if all my work and love just went to waste in the end. 4 years is a long time to me. To anyone. And we're so young. But, I feel like I'm wasting my time, and there's a guy out there for me that would be there for me when I need him. I'm not a clingy person, I'm the opposite. I never call him, unless I feel like I need to or I'm in a good mood, I text him once a day or maybe once a week. Not a lot at all. And we only hang out like once a week. But if it was up to him it would be like twice a month! Is it me? I mean, I'm the same as I've always been. I'm just like him, only female. We have the same humor (though he's SO immature!), if anything I've gotten better looking cause I've matured, I'm easy going, chill, funny, and I adore him and it shows! I look at him like he's heaven and earth. I'd do anything for him, cause I love him that much. I just...don't know anymore. I feel lost and angry and like I'm wasting my time, but I love him too much and I feel like I'd regret it if I left him. I asked him to come over today so we could talk. I have NO idea what I should say. What should I say? I want to make it short and sweet, to the point, cause I'm not very good at long speeches lol. Any advice or help?
