How the hell............

Can anyone enlighten me as to how the hell you deal with the fact that you love someone and want to share alot of times with them, but it seems that they want to limit the amount of times they spend with you? That really, all you want to do is see them and plan to do things with them when you have free time and yet it seems, they only want to see you on their terms...When I see the person I love I feel happy and content in his company. When I'm apart from him, I miss him so. Am I ridiculous or what?
