Feeling stuck

I feel like I'm going to explode. I've been in a relationship with my boyfriend/companion for almost 15 years. We both have medical issues and basically live together out of convenience. He doesn't talk, communicate or share feelings,  EVER.

In the past couple of years he has become obsessed with guns. He spends 80% of his time while at home watching gun videos, cleaning his guns and shooting them. I am not against self defense but this has become his only interest. I feel so alone and suffer PTSD from my ex husband who tried to kill me. He doesn't seem to understand how difficult it is for me to be around all this negative energy as I'm also an empath. He's not spiritually awake at all. I can't leave due to my medical conditions and lack of funds. He talked me into moving where we are now about 10 years ago which removed every friend from my life. I literally sit on my couch with nothing to do while he plays soldier boy. Recently he built a couple of ghost guns for a friend who is not allowed to own a firearm. I spoke up about it and now he keeps everything secret from me. I would flee if it wasn't for my 2 dogs and 2 cats (the only family I have). 

Any ideas or suggestions? I'm better than this and deserve better treatment and communication.
