"I love you"... no you don't.
"I miss you"... you miss what we had.
"I'll never leave you"... yes you will.
"I need you"...you need me to feed your ego.
"You're the only one"...I'm the only one who is blind to the fact that you are cheating. 
I love you. I need you. I want you. I'm the one who will never leave. Because after all the hell you put me through, I'm still here and I'm still in love with you.  I'm always gonna love you....but you can't see that. You can't see that I will go through hell and back 100 times before I give up on you. I gave you my heart and as much as I want it back, I don't want to have to start over. So I stay. I stay for me, for you, for us. Even though I know you're out here doing me wrong, I ignore it. Because one day I want a family with you. I want a future with you. I wanna be with you for the rest of my life. I'm willing to waste all my time, on you. Even though I know I will never be good enough to satisfy. I'm always going to give 110% of myself to you. To make you happy. To make you smile. Because I love you.
