The bubble made by a thread

"But I think for two people, to really love each other. To really commit to each other, it has to be an act of will or a decision.
 

And I think, two people have to live that decision every day. 

Even when things are hard
and you feel like giving up, you have to hang on to that decision; that choice to love each other.
 

Even if it's only by a thread".
