Trust, Money, & Problems..............

Last night I got a phone call that I care not talk about but I feel I need to get a few things off my chest to warn other. Learn from me.
A friend of mine (not sure how good a friend I really think he is now) about 2 years back started playing gambling sites for extra money and fun. He started winning right off the bat and became so turned on by the idea of winning that over the years he has found it hard not to bet money he doesn't always have. Luckily he has almost always come out ahead or ended up ahead in a short period of time. He like to work the tables now as a way of paying his bills, risky but he has been ok just barely scraping by but avoiding the "day job" we all wish we could. Anyways I let him gamble under my name those years back and the accounts (I know so stupid) had my bank account info that he has always used to transfer money to me that he has borrowed or owed to me in some way. Never had a problem till a few days ago. He called and was hysterical that he had done something wrong ow so wrong but could not tell me. I got aggravated and told him to text me whenever he felt he could talk about it to actually tell me what was going on. I took it as him trying to ruin my night because I was out having fun and he wasn't but when he texted me my heart dropped. He told me he had taken a large amount of money from my bank account and lost it all on a high stakes table. I was livid with him but what could I do for all I knew the money was gone. More came of this situation I care to not talk about but in all this I expected the worst. I expected to go home and find my bank account cleaned out. First thing I did the next morning was go to the bank to see what transactions happened in the past few days and found a few from where money was taken but nothing to the amount I expected, Thank God. I spent a good portion of my morning canceling my account and transferring my money to a new account that he dose not have access to. I felt good walking out of there knowing I had avoided a worse situation and that I could fix it, I wasn't helpless in this foolish mistake.
So please I know its something everyone knows but we don't always do what's best but don't let others have access to your bank accounts for any reason. Some of us trust people too much and that exactly what I did.
