Never think of what could have been.

Take the chance when you have it, with anything, not just relationships, with friendships too. Take risks. Life is boring when you don't take risks. If you don't, you'll regret it later on. You'll always think how things would have been different if you would have just said that one little thing, or done that something you wanted too do. That thought will always be in the back of your head. Even if its most likely the wrong thing to do, and you think you know that person really well and you think they'll react a certain way, just do it anyways. You never know what'll happen until you do or say it. And if it ends badly, at least you'll have the reassurance that you tried. And you shouldn't regret ever trying. You did what you could, and thats all that god wants. Just always remember, if a person walks out of your life, God is always there, no matter what, and he loves you unconditionally, he loves you more than anyone ever could, more than you can even imagine, and thats all that matters.
