On The Real: The End of A Man's Life

Have you noticed that when a man enters a long-term relationship or gets married, he'll tend to say that his life is ending? And have you noticed how when a woman enters a long-term relationship or gets married, the assumption is that she is beginning her life? Why are these two concepts of relationships on the opposite sides of the spectrum? For males, I think it is because when they get into a long-term relationship, they are not able to "play the field" anymore and also, they are not able to engage in as many activities with their guy friends anymore, if they were to be a bachelor. But, women are like that too. They go out to have fun and "play the field" just as much as guys do. And if a women were to get married, in my personal opinion, would lose more in life than a male would. I say that because, if for a example a specific woman were to have a great career, when she gets married, chances are she won't be as actively into it as she would be if she was single or not married. So let me elaborate, when a woman gets married chances of her staying home with the children are pretty high, if she chooses to have children. So if she were to have children and stay home with her children, then she'll likely quit her job. But when a man gets married or into a relationship, all he really loses (most of the time) is his ability to date and have sex with many different women, and hanging out with friends a lot. But his career is still intact. And chances of him staying home and becoming a "Mr. Mom" are pretty slim because of societal influences of "masculinity" in males. So there is a big double standard between males and females, and I just wanted to address it. Comment on how you feel about this.
