Do I Have To

You may wonder why I love you when you treat me the way you
 do
You may wonder why I want you when you want someone new
There are things in life that I can't explain like this 
love I feel for you
Do I have to have a reason to go on loving you
Does the robin have a reason for every note he sings
Does the violet stop and wonder why it blooms in the spring
There are mean times that just happened and we don't know 
why they do
Do I have to have a reason to go on loving you
Do I have to have a reason to go on loving you
