Hope I really believe that you two need to have a friendly conversation about your life,relationship and spending..try to approach him in a nice way possible about his addiction,don't sound like a villain so he won't get defensive,there are many ways to kill a cat like they said.Communication is the key to every differences.Prayer alone won't work if you won't speak with him about the issue.Tell him your real feelings,above all,trust him if if he is trying to get over IT.Gambling is like a disease,sometimes a victim can heal or not,it takes a lot of love from you and an effort and dedication from him.Above all never give up on PRAYING it works magic & miracles.GOD have ways we can never even imagine.GOD BLESS YOU BOTH.
