I'm in an abusive marriage and I cannot leave him for a year - need help coping

I have a thread on this topic in the relationship forum, but I need help coping from people who have also been abused and/or are in an abusive marriage/relationship.

Here's my thread:
https://psychcentralforums.com/relat...m-falling.html

The problem is, I cannot afford to leave him for another 10-12 months. We JUST renewed our apartment lease this month, and I cannot afford to move out and carry the rent for two places. I cannot afford to move out until next year anyways, after I've saved the money needed in order to rent a new apt and move all my belongings.

In the meantime, I am NOT telling him of my plans to leave OR to divorce him, for my own self protection, sanity and mental health. We cannot undergo a separation for the next 10-12 months within the same apt. I do not trust that it would be amicable or even remotely manageable.

I need help coping with this situation, that I know is abusive (off and on). Right now, he's being an angel, but I know it's just the honeymoon phase of his abuse.

So, how do I cope with this secret and with being with him, while I save money I need? I am not going to a shelter, so please don't suggest that.

Thanks so much.
