Fuck, Yes. Could not agree with you more. Marriage means absolutely nothing to some people anymore. Why the fuck even get married if maybe you'll change your mind down the road, or just because you feel like it, or you think you've outgrown your spouse, or you're bored with them, or now you're too good for them.
And divorce affects more than just those two people. It makes a significant impact on any children involved (minor or adult), and the families involved, and mutual friends. So if you go into marriage with such a casual self-centered attitude, make sure the person you're marrying is perfectly fine with the possibility of being rejected and abandoned at some point.
