My husband keeps going to the pub after work every night?

He then comes in half drink hurls verbal abuse at me then goes to bed. I have been to work all day and dont need this. We have been married for over 20 years and are both in our late 50's I dont know why I put up with this but am really getting fed up with it now but think its too late in life to change. I dont really wnat to live my life as a single person. What do you think I shoud do
