If you borrowed the money, you owe the money. It's as simple as that.

If you borrow $5 from your mate, you pay it back. If you borrow $5K from the bank, you pay it back. The principle is the same.

You signed on the dotted line for that money, you asked for it. No one put a gun to your head and shoved the money into your pocket.

Grow up and suck it up. Stop blaming your own failures on others. Be a man and live up to your responsibilities. It's people like you who make life difficult for everyone else.
