In my opinion it was the false behaviour of the boys, because they are the father and they must take responsibilty. But despite this fact, they leave theirs girlfriend and want to start a new life without the baby. The excuse 'I don't ready to be a father' isn't okay, because the boys had fun by making love und now they must accept the consequenzes. I think it's the worst to leave their pregnant girlfriend, because they need mental support, specially before and after the birth, and not to be a single parent with a baby. All in all i can't understand the boys and i think it's exorbitant waht they have done.
