Male Dragon Female Monkey Run Around

I'm a male Fire Dragon and she's a Metal Monkey. We've been friends for 8 years and very very flirty with one another but she went from a husband to a live in boyfriend recently and never said a word to me. She's still very comfortable with me but denies any attraction to me. I told her I'm in love with her last night and on goodnight she kissed me on the lips for the first time. What is this monkey business about?
