OP,
Just because someone is pleasant in work does not mean its hard to believe that they are different at home.
People understand very well what goes on behind closed doors is often vastly different.
I think you should approach HR.
They are used to staff and their problems.
I think you should also contact Woman's Aid.
You need to see what your options are.
Of course this is scary for you.
The thing is, which scares you more?
Leaving of staying.?
He's a nasty abusive man.
He has put his hands on you OP.
That is Domestic Violence.
Just because he didn't leave marks, doesn't mean it isn't domestic violence.
Please be very clear on that point.
