Yes you are definitely being abused. I'm a domestic abuse survivor. He will continue to abuse you and it could be escalate. You mentioned you don't want to bother family. However if your family is supportive please contact them. I'm sure they would want to step in and help. I quit my job when I was with my abuser due to injuries caused by him. It was difficult leaving without an income. There are people out their who are willing to help and put you on the path to freedom. It will get better.

It's still abuse if he doesn't leave bruises ; pushing, shoving, threats.

I agree with others please don't tell him your thinking of leaving. Can you make calls from a trusted friend, neighbours cell phone, payphone?

Remember it's not you're fault.
