<human>: I have been in a perfect relationship for 3 years, I live with my boyfriend and he's an incredible man. He helps me emotionally, financially, and in every other way. I do the same for him, we are just there for eachother. We make eachother laugh, we have a fun life together. I love him with my entire heart, but there is just something missing. I miss him when he's gone, I daydream about our futre. What is wrong with me? 

If I were to leave it would be a world of heartache for both myself and him, and it could be the biggest mistake of my life. I just know there is something I'm suppose to feel that I'm not feeling. 

Does anybody have any experience with this?
