I have been through this. Nothing is wrong with you. Sometimes with any mental illness we forgot things. My ex and I at times could not figure were I was spending the money. We would then look at all the bills for the month and realize I was manic during those times and was not spending the money on bills and food but rather on things that did not matter. I was buying wine and things like that. Due to me we got behind on our bills. We lost our apartment and our lights in the apartment got turned off. I suggest looking at the times when you got behind on the bills and try to figure out what your mood was during that time. It may help you figure out where the money went. I hope things get better for you and your husband.
