My husband drinks a lot and also gets abusive after drinking. How do I help him get rid of this habit?

Please send him to counselling and also get a protective order to protect yourself! Prevent him from drinking again and try communicating to him when he's sober and reasonable. Let him know you are keen to help him and face the problem together as a couple. Encourage him to go for counselling and let him know they you cares. Be positive but also remember to protect yourself.
