You are a gentleman and doing the right thing! Good on you! Even though some men don't accept this, women do sometimes just want to be great friends with a man. I have the most loving partner and he means the world to me. We support each other in every way and I would never do anything to hurt him. He knows that my closest friend, apart from him, is a very handsom young man, who is far younger than me and who has been my best friend for over 25 years now. He has recenly married and I am absolutely delighted for him and his bride, who is also becoming a lovely friend. So, friendships between men and woman can and do work, even longterm. Unlike Loosehead, try to see the positive in her behaviour and let things go their natural course. This way, if you don't end up in a loving relationship with her you may still end up with a great friendship. I wish you well.
