I had a month long period during a depression/mixed state where I resented my husband and hated the fact that I ever married him. But I was also a bit delusional and believed he was trying to control me and turn me into a stepford wife through my medication. I never did anything about it thought im one of those people who just wouldn't break up with someone no matter what...But honestly I would definitely not make any decisions while you're so down. I know you know this but everything is so distorted when you're depressed. I think you need to wait until youre a bit more stable if you can and if you still feel like this then decide how to proceed.
