i think there might be a little more at work here than just money...
DW, you have said that you are feeling very depressed. Maybe you could make an appt. with a doctor and discuss this.
Being with a very manipulative addict, especially an abusive one, can really do a number on a person's self esteem and can cause depression. It can be very hard to figure out what to do and to trust your own instincts when living with an addict, indecisiveness is a codependent trait. It can also be very depressing. Depression can keep a person frozen and afraid to act.
I know that being with someone who said one thing and did another continually really did a number on my head.
