My fears

I feel that in life in general, monogamy is a double edged sword of happiness and torment. I wish it were just complete fairy tale ending and I found my princess and that was it. But what happens when previous princesses contact you? What happens when that hostess you hooked up with a year ago is back in town and wants to meet up? What happens when that bi girl is in town? What happens when you sit down in a cafe and you can hear what the group of cute girls next to you is saying about you in detail because they think you can't understand? What happens when you go to step into an elevator and the doors open and a really cute girl is there and she sees you and starts bushing and then gives you the eyes and you know that if you weren't trying to be 'Mr.monogamy', you would be eventually sharing a beautiful moment and a beautiful memory with a beautiful person? What happens when these things happen, but at the same time you know you really like the person you are with and don't want to ruin that?

Frustration happens.

I'm just curious why we have these social rules in place. Who was the first person to say, "one only", and then everyone else followed that rule.

At the same time, the last thing I want to do is totally abandon social norms and end up in a skewed reality that is so departed from everyone else like this guy.
