How to know when you should get a divorce and when you should try to work things out, is a complicated question. However, there are some things that can't be fixed or that you can't take responsibility for. Generally, if you are married to somebody who has severe issues; alcoholism, drug addiction, gambling, physical abuse, things that affecting the danger of your family and your health. Then it's time to leave. When there are issues that come under the umbrella of "fixable," that's more along the lines of if you are willing to do the work. Frequently, I see a lot of people that come into my office that are talking about divorce and they need to understand that the relationship that they are in, it's going to be the same situation, a different day. So I encourage people to take inventory of the issues that are happening in their marriage to attempt to address those issues, and not to just complain and think the grass is greener. In general, the grass is green where you water it. However, if the marriage is so broken that you spend all your time daydreaming and being free of this situation, I would strongly suggest consulting with an attorney.
