A New Friend

What happens when one has feelings for the other but he knows he can't love her for she loves someone else.

Friends since the beginning but is that all they are? Can he keep his feelings to himself or will he confess what he really feels?

When I first saw her, I knew I never wanted her to leave. How was I supposed to tell her what I feel? If she was my Bestfriend?

Thats what we told each other. From the beginning till the end we will always be bestfriends.

Then one day I felt ready to tell her but someone beat me to it. I knew he liked her and she liked him. What was I supposed to do?

Tell her I loved her? I couldn't do that. Could I? But if I did will it change anything? For better? Or for worse?
