I can comprehend only 2 reasons to marry, 1- One wants to raise a family of his own. 2- One meets a person, one wants to spend rest of their life with.
If both these are not there, your career is more important than raising family, you are not really in love with potential spouse to that degree, then why ?
Ofcourse, there is peer pressure but is it worth the effort?
I am so happy that legal rights of inheritance, beneficiary and such only make one eligible if he or she is in s legal civil partnership with another person. That is the reason of getting married right there.
I think companionship is a rather important reason. I'm not referring to the romantic (bordering on saccharine, actually) bollywood/hollywood "I want to spend the rest of my life with you" type of love, but companionship as in having someone to to talk to and share life's milestones with as you age.
Back to the topic. Many reasons to marry:
-start a family
-fulfill physical/emotional needs
-maintain the status quo / fit into society
-financial security (to some extent)
-share life with the one you love or look up to... someone who brings out the best in you...learn from each other and become a better person overall. A good marriage = a happy you. Happy you = higher potential to do well in all other walks of life.
-have someone to depend on in times of distress, sickness, failure, etc.
Can't wait to lose half of everything I have worked for, don't like my mom living in peace, don't like myself living in peace, want to start whispering in my own home, don't like hanging out with my friends anymore, getting laid for taking out the trash, and I love SUVs, what kind of a man does not like SUVs?
