Hi whataguy,
I, too, agree with what the others have said. I know it's not what you were hoping to hear but everyone is just trying to help you since you asked for opinions. Anyone here reading what you wrote, can objectively see the problem, that you are feeling.
I believe you are experiencing transference and the more you think about and fantasize about this person, the more real it [you'r love for her] becomes in your head. Maybe you remember every little thing that she said to you and maybe you read more into it, than was meant.
Once therapy has ended, that will probably be when you will know your answer for sure.
Wishing you the best.
