You are not a burden.   I have lived with the addiction to gamble and I know it’s terrible capabilities but I also know that I will never live with it active in my life again.  
With that knowledge I hope to take your burden from you because I have learned how to lay it down.  
I am glad that you have said that you love your husband – it is a question I often ask.   It means I know the route you need to take for you to survive while you support him.
I hope your support group is good.  
I am glad that you have found us too
