I loan money to my brother and cousins all the time... They pay me back quickly and haven't ever had any problems with it up to this point except for an isolated incident. I loaned my brother $3k and i was suppose to get it back in 3 months, which at the time was fine because i had the money to spare. Anyways he kept ignoring me, not answering my calls, etc... So i finally went to his house late at night and got in his face to tell him to stop all the bullshit. He told me that he owed money to a couple of bookies and was worried that if he told me the truth that i would just take the money back.
Anyways i put him on a payment plan where he would give me less money weekly and pay it off like that. Family will still be family as long as u approach them in an appropriate manner and just talk to them.
