Why won't my ex boyfriend pay me the money he owes me?

The saying goes "don't lend money to family and friends!" If the person doesn't bother to pay you back (and most don't) then there will always be that between you and you'll never feel the same about the person again. Remember, you work hard for that money! Unless you signed a contract with a witness (most people don't when it's just a personal loan from your bank account) then you are stuck with not getting your money back. Sorry (I've been stung before but learned from the first time around.)
