If fate has brought two people together then despite everything they will be part of each other's life , even if one of them or both fails to realise this. They are brought together so that they learn from each other and grow. Maybe by staying together or by being apart but never completely out of each other's life. They want it or not, putting their own choices and decisions in between them, but if they are fated to be together then somehow they will stay connected, until their time to be together is over and fate puts them apart.

Your choices and decisions only gives you power of what you chose to do, but what you shall have is completely Fate's plans. Once gone, you can't bring them back because when you had them you didn't valued them and now your time to be together is over. Maybe this is the lesson one ought to learn "To value things you get, while you have it because everything that's been sent your way is a blessing from God but It might not be with you Forever. So, Cherish it." They might make you or break you, either way they teaches you, which is a valuable experience for life. The only thing you can do is embrace while you have it and grow up from following what you learnt from it when you had them and when they had gone. No one knows what future holds, so feel blessed with what you have today and value them because once gone , you never know if you will ever have them back or not.

If you are brought together then stay together and grow together because nothing lasts forever and before you can even realise what's happening you will find them fleeting away from your life, you can never be able to reason out why and how....and One day they will be just your Memory.
