Is this a norm in France, and what should I do?

I am a traducteur, I live in France. I translate a bit of everything: catalogues, contracts, manuals. I read detective novels, and my wife left me six months ago. I worked hard, and decided that I needed a break, so I hired a little g�te near Cannes, and took a TGV there. I am not rich, but I splashed on the first cl ticket - my only luxury. The carriage was empty, so I was surprised when a beautiful woman chose a seat across me. She asked me to help her to open a zipper on her top. Then she said that she'd like some tea with milk, and I got it for her, and bought a meal for us to share (though she refused it). We talked about my nervous condition, and about my eating habits. She seemed to be really interested. She quickly spotted my name and address on my luggage (Fran�ois Taillandier, 18, rue Mouton Duvernet, Paris). She tried to guess my age (said I was 39, but I was 38). I told her about my life, and my holiday. The conductor came to check our tickets, and he noted, too, that she was not on her igned seat. I asked her why she choose a seat across me, and she said I was her type of a man. It all sounded so promising. But then she borrowed my pullover and used it as a pillow, and went to sleep. She slept and slept, and now we are almost arrived, and she is still sleeping! I thought she was interested in me! But if she was, why did she felt asleep? And if she was not, why on my pullover? I am so confused, and I don't know what to do or say. What should I do?
