I choose to love you in silence…
For in silence I find no rejection,

I choose to love you in loneliness…
For in loneliness no one owns you but me,

I choose to adore you from a distance…
For distance will shield me from pain,

I choose to kiss you in the wind…
For the wind is gentler than my lips,

I choose to hold you in my dreams…
For in my dreams, you have no end.

Rumi

The question is how to check you really love someone?
