"if you love someone set him/her free?

If that person doesn't love me back then i would really set him free. And if loving each other would hurt us more rather than help us grow then i would set him free as well. But when i know how much we love each other, no matter how whard the situation is if i know that we can make it and we would be happy, there's no way i would set him free.

It's a true statement. If you really and truly love someone then the only way it can ever work is if they love you back freely and without restrictions. Remove all the controls. It can be equated to trusting your dog outside without a leash and just knowing that he will stay there even when given all the free will to walk or run away. 100% trust
