While living in France, either on exchange or temporary stay, one might come across the possibility of dating a French person.
I recently came across this issue from a good friend of mine, exasperated about a few dates she went on and confused about the body language.
If someone is starting to touch, kiss and text a lot it's a sign that the French person sees you as more than just a 'date' and considers it a 'for sure thing'; as in they really want to be your boyfriend/girlfriend.
A french person will not spend an enormous amount of money, shower you with attention and think it will go no where; also; while they are doing this- be aware they are not doing it to someone else. If you find yourself in the position where it's too serious from their end and you're not in the same place: stop giving affection. Don't go out with them alone more than once a week. express that it's a cultural difference and you enjoy being around them but you are not ready for a relationship. It's rare to have sex and not have it be something.
Enjoy dating the French; for me they tend to be the most receptive and comfortable in a relationship.
