That's the most complete and utter bullshit i've ever heard in my life. My parents got married at 18 and 24, i don't see them getting a divorce any time soon. I've been with my bf for half a year and we've been friends for 1 year anyway we're getting married in a couple of years after uni, sure some people break-up with their bf's but that's not to say that all couples do, people like you make love seem so simple, but you probably don't even know the meaning of love anyway, and please do realise not all guys are careless idiots like you. My only advice to you and people who think like you would be to grow up, as in, get a brain.
