How Do You Decide?

What do yuo do when the person you love is no longerthe same? When you stop loving them but they continue loving you? When you still care and they say they don't want you to go. When you still care about them but as a friend. When you're not sure but there's just so much stuff clouding your judgement. When you really don't know what you want or feel because there's so much stuff gone on. When you don't know if it's good for either of you for you to staiy together. To have to make the decision to stay and always be unhappy and never know if you'll find the right on or to leave and break their heart and hurt yourself and feel like you're a piece of shit. To feel as if you're using them even though you're not when they take care of you. How do you decide? Between what's right and wrong, between it all? How do you decide to break someone's heart like that?
