I'm at a crossroads

I'm in a very complicated situation right now. Tuesday evening through most of yesterday I felt strong enough to face it. But now I don't know. I love someone. But he has a lot going on in his life. I can't go into to many details. I want to fight for him, but a part of me feels like I should let him go. I don't know what to do. At the most all I can do right now is be patient. All I know is when we're together, we fit together. But when we're apart, he has so many things outside of us getting to him and it winds up affecting us. I know I have to make a choice and he has some to make too. I just wish the choice was easy.

I don't think anyone can really offer any advice. I mostly just needed to let this out.
