I hear you. I have a friend whom I believe likes me like a girlfriend, but it's all been platonic so far, and the other night I asked him to do something and he had other plans.
I cried. Not because he's done anything wrong but because I realized that I had feelings for him and it scares me to be so vulnerable again after all I have been through.
I have no wisdom except to say that maybe we have to give ourselves permission to love and be loved. God knows, I know very little about it anymore.
