I have two huge examples if how you really need to like and see yourself married or you'll screw up your life: my father and my wife (really..). My father was like most of you guys. He liked to travel a lot (he is a photographer), and in one of those trips, he knew my mother. To make a long story short, they made me, got together, and soon he had a family, and with it a lot of responsibilities. He hated it, his constant trips ended, now he had bills to pay, a son to feed, soon had a 'real' job, I grew seeing them both having a miserable relationship, and now they barely talk to each other, with him constantly blaming her for his shitty life. Ok, his fault too, but you got the idea. Bottom line, he wanted a free lifestyle and ended up stuck with a wife and kids. Wife and kids demand attention, so if you dont want to give that, forget marriage.
As for my wife, I just got lazy, and I am too tired to write atm ehhe
