I think we have more freedom to choose here. If I am dating a guy I am in love with who my family approve of and something goes wrong (example he cheats) I would just end the relationship and my parents would be supportive of that.
I believe in some cultures, once you commit it is difficult to get away from that person if they hurt you
I only date one person at a time and if I don't see relationship potential, I would not sleep with him and it would end within a month. Everyone is different though. That is how I date. I wouldnt date a guy who is seeing other people ever
