Maria,

This is very unhealthy behavior on his part, the gambling, and especially the abusing. He can say he will change all he wants, and he “loves you, but this is not love. Willpower alone will not stop these very destructive behaviors. He needs some kind of intervention, such as Psychotherapy, anger management, Gamblers Anonymous. Unless he gets professional help for these issues, they only get worse. I fear for your safety.

Please get to a safe place, and do not have any contact with him until he gets the help he needs. He is a very unhealthy and dangerous man.
