I really don't know.

I'm so confused.
There's this special someone. Who means the world to me. Who i don't want to lose. This person stayed with me through ups and downs. And loved me since day one. This person means a lot to me. But recently, I've made more mistakes than anyone can imagine. And I've changed, for that person and for myself, because i really don't want to lose us.
But I'm starting to doubt if i really still want us. I felt really hurt and stressed, not only today, but for the past week. I really hate that feeling, and i don't want it to happen again. Since I've changed for us, that person, too, has flaws. Some major ones in fact. And i really want that person to improve on those, I know it's not possible for something to change completely and i understand that nobody's perfect. But it has just been too much for me to handle.
On one hand, I want us to be gone because if this continues on, its really unhealthy. But on the other hand, i love and care for that person more than i do for anyone else.
Looking back, we were so happy. What happened? People change.
I want that person to be happy because that's what truly matters most. Even if it comes with a risk of me losing that person. That person still has the capability of finding someone better. Someone who is prettier, smarter, cuter, complaints lesser, don't take things for granted, thinks better, someone who actually deserves that person.
Should i give this up? Or go on and see what happens?
