I was in a very long long long relationship, and after the icky break up period, there have been lots of crazy emails and things going on. One of which is our banking situation. We each had our own checking accounts, but decided to make the other a signer on our account as well. Naturally, once the dust settled, I went straight to the bank and said take him off my account. Come to find out my bank won't do that- I had to close my joint account and open a new single account. No biggie. But I've come to find out that he hasn't done this. Well over two years. Years people! I was in mild shock when the teller asked me if I wanted MY deposit to go into our joint checking. WTF!?!?! Now, the moral dilemma, (my friends come down on both sides) is do I close "his" account and teach him a lesson? Sigh. If only I lived life that way. But, it has been weeks since I found out.....
