It's natural when you truly care about someone to envisage loss and treason. If your girlfriend let you go to a strip-club without fear you will accept a lap dance or even more, I can guarantee you that she does'nt give any shit about you.Any healthy person is supposed to be with people that they can trust not to do that - without them being under surveillance.
Not sure.I noticed you're from France. The worst, most jealous guy I've had to deal with was from France, too. I know two people does not a mean a sample, but perhaps behavior like that is more culturally accepted there?
