I Love Him But Can't Have Him

The fact that any motivation I get to do anything is coming to me because I love someone (I cant be with). Cleaning my home, getting out. And all I know is they are in mind and heart. And they motivate me and yet I probably dont do the same for them. I just want them to be happy and healthy and enjoy their life. Even if I'm not the reason they smile or the reason they are excited for a new day. Even if I cant be theirs/ them be mine. And then when I'm in the middle of improving my life because I got motivated by them, I start to shut down and get sad cause I know the way I feel wont ever be matched. Then i really just start to feel lonely and heartbroken. Talk about fun..
