1. Physical abuse.
Nobody deserves to be hurt in any way. There are no exceptions to this rule. Do not listen to any justification or any blame. If you or your kids are being hurt, then no justification will make that okay. Here are some questions that you need to honestly ask yourself:
 Has your spouse isolated or tried to isolate you from family and friends?
 Have you ever had to call 911 because of violence?
 Has your spouse ever sent you to the hospital?
 After harming you, does your spouse apologize and promise that it will never happen again?
 Do you try hard to do every little thing perfectly so that you will not be hurt and your spouse will not lose his or her temper?
 Do you feel like you never do anything right?
If you answer yes to the above questions, then you might have battered spouse syndrome, which is also characterized by constant forgiving on your part and a reluctance or inability to leave the situation. This situation is grounds for divorce, without a doubt.

2. The Affair
You discover that your spouse is having an affair. Do you leave? Do you stay? It depends on your personality. Think carefully about why you would stay. Is it because you really want to forgive your spouse and move past the affair and rebuild your marriage? Or are you staying with an unconscious desire to constantly punish your spouse for what they did? Be absolutely honest with yourself. The latter motive is not a good reason to stay in the marriage. Similarly, if you are the spouse having the affair, think seriously about why you are cheating. Think about what you really want. Think carefully about what you will be giving up-children, stability, etc.-and what you will be gaining.

Here are some other problems that you and your spouse might be experiencing in your marriage. Hopefully this list will help you work through understanding why you are considering a divorce, and whether you want to stick things out and work through the issues, or whether it's time to end your marriage.

1. Problems with sexual intimacy.
These problems cannot be ignored forever. If you are going to stay together, then you need to work these out.

2. Problems with temper.
Does one of you blow up at every little thing and find it impossible not to become overly emotional and heated during an argument? This is another thing that has to be solved for a healthy marriage.

3. Problems with selfishness.
Whether you or your spouse is selfish, this will ruin your marriage. Ask yourself if you are being selfish, if your spouse is being selfish, and whether or not either of you is willing to change.

4. Problems with honesty.
If either of you are dishonest with the other person, the foundation of trust, that every marriage must be built on, will start to erode. If that trust is not there, then you have a serious problem.

5. Problems with respect.
If one or both of you does not respect the other, then you are going to have a lot of difficulties. If you want the marriage to keep going, then you need to get to the base of this problem so that you can understand why one person treats the other so badly.
