My fiance's dad made a pass at me?

My fiance and I have been engaged for 2 weeks, we traveled to Australia so I could meet his parents while we both had vacation time at work. My husbands dad is rather straight to the point and kind of a Don Juan sort of guy. That is probably why his mom and dad are divorced. My fiance went out with his friends last night for a guys night out just to catch up with his friends. My fiance dad was out on a business meeting so i thought I was alone. He came home while I was reading a book in the living room and sat down. He asked me if I wanted some wine and I said sure. We had one glass and he started telling me how my son was lucky and what a very beautiful girl I was. Also, he said that it could be very dangerous to leave such a lovely, attractive girl alone to be whisked away by another man. He honestly sounded like someone out of a movie. I started feeling very uncomfortable so I told him I was going to bed. He than asked me if I would like some company, I pretended i did not hear what he said and turned around and went to bed but stayed awake until my fiance returned. Is this something I should tell my fiance or is this just him being flirty? I am really not sure what to do with this.
