The question has been asked, why should we commit to one person? People who declare their love for each other tend to want a level of commitment from each other. It shows that they have mutual respect and most people don`t want to share the one they love. Then there is the risk of STDs. Growing up I observed "grown-ups" behaviour and this led me to realise that no-one can be trusted, husbands cheating and leaving their wives to bring up two, three or even four children on their own left a nasty taste, women cheating etc, brought me to the conclusion that commitment doesn`t really work. The last relationship that I was in was a "commited" one and as such I really did trust her. We both know/knew that nothing is permanent. One falls out of love with the other, the rot sets in, they start looking at other potential lovers and someone always gets hurt. There is no reason or justification for cheating, if you no longer want your partner you should end it before taking on more lovers. The fact that he/she is having sex with others means they don`t love their respective partners. Therefore it is not a relationship. Just another sexual liason. I certainly wouldn`t want to be with someone who has one or more other sexual encounters. To put it bluntly who wants the love "of their life" to allow lots of other men to ejaculate inside them and then return home as if nothing had happened?
