What does it takes...?

What does it takes for someone to love you? 

It is not about being selfless or putting your significant one first, I've tried that.

It is not about loving someone with every fiber of your being, for I don't think anyone could ever love more.

It is not about taking his hand and being there and having his back through his wildest dreams, 'cus there's no road I haven't covered.

Is not about patience or devotion or silence or understanding or unconditional forgiveness...

So please could someone tell me...what does it takes for someone to love you?
