DonnaJ...have you considered calling the National Domestic Abuse hotline to get some support and some resources in your area? Also, you might consider calling a shelter and seeing what they can offer you.
You are being abused.
You can get out.
I would advise you to keep to yourself as much as possible, and not share any details of your plan to escape with your abuser, as this can trigger further abuse.
Please know that there are options to staying there, waiting for the senior housing people to call you.
