Many people obey their girl friends more than anyone else.
What if their girl friend insists you to stop gambling
Will you Stop 
What if their girl friend insists you to stop gambling
Will you Stop Why will anyone become a slave to another because you want to satisfy an urge of a girl? No one has to obey anyone against their own standard. If you want to stop gambling, do it because gambling affects you and not because someone is forcing you to.
Often times we never realized something until someone forces us to realize it. A gambling addict will never admit he is addicted unless someone had clearly pointed it out. In this case, if your girl asked you to stop gambling, or even force you to stop, threatening you a break up if you don't listen, simply because she is concerned for you. She shouldn't have a problem with your gambling activities if she isn't concerned about the possibility of gambling addiction.
How about in cases where addiction is almost eating up your gambling habit and she decides to help by suggesting you stop. Women naturally think out of selfish wills no doubt but in some cases as well they mean well for the one the claim to love. I think other than taking a complete stand on how one will react to their suggestions if the ask their lovers to stop their passion looking at her reasons for asking you to stop gambling will decide the next action
Don't be sexist even male think out of selfish wills. The male inconsiderate behavior of continuing to gamble in spite of her gf asking him to stop gambling is a show of selfish will.
