Being married adds that little bit of stability and something to fall back on when relationships get hard.
However, when they are too hard it makes it complicated. Really though it would be fine if we weren't so financially intertwined.
I'd say just get a pre-nup, and give every relationship your all...that way you can give your all and know you're doing your best, with no regrets.
That's the only way you get a head in life...give it your all, at work, in relationships...you have to be open to change and to bettering yourself.
But, if you really hate the idea of being tied down and committed to one person, well then it's not for you! But then neither is any serious relationship. Which is fine, and it's awesome to know that about yourself a head of time!
