OK perhaps I was too harsh on your female friend. However I think this comes down to a question we have discussed previously: Can a heterosexual man and woman maintain a close platonic relationship? I have argued generally not. Thus the current state of your relationship - one where you are a confidant on a daily basis about private matters - in my opinion cannot be sustained indefinitely. Either it turns into a relationship or it goes away. It's just my intuition but I feel she must have known you had feelings for her - but I could be wrong about that. Is there a problem with just laying it all on the line and telling her you have feelings for her? If she has had hidden feelings for you, then that is good news for you. If she is not interested, wouldn't you want to just know that and move on? You might as well just lay the issue to rest - that is, if you can accept the possibility of rejection.
