Question: What are the usual reasons for divorce?

Disagreements, and not-well-thought-out plans for the future.
Abuse and/or just done with the marriage and/or not wanting the marriage to work anymore.
I don't know. Married too soon, abuse, cheating, unwilling to work things out.
Bad sex.
Unfaithfulness. Arguing over money.
Parents that are too different to get along and that cannot compromise on the most serious of issues. Parents that cannot find a better solution to handling an issue than fighting all the time.
Arguments.
Funds, cheating, substance abuse, spousal abuse.
One spouse cheated.
Parents are irresponsible and have sex with others, then think they're in love with the other, "exciting" person.
Differences of opinion, or a new lover in the picture.
Fighting over money, or one person is abusing the other.
Fighting, disagreements.
They didn't wait on God's time but their own and rushed into it to find differences.
Selfishness: People are frustrated with their spouse for not doing it their way or they cheat on one another.
Cheating. Abuse. Financial reasons. Etc.
One parent slacks off, cheating, breaking laws, etc.
Cheating or fighting.
Probably money. Especially in times like these.
Arguing a lot, unhappiness.
Selfishness, miscommunications that lead to fights, unfaithfulness to spouse ... mostly selfishness.
I'm not really sure but I think that affairs are quite common.
Unhappy marriage, no longer in love, more severe and personal issues such as beating/abuse. Pressure from family, money problems.
Not good sex.
"Change."
I don't know ... I'm only a kid. But maybe because of financial problems.
Falling out of love, adultery, finances, etc.
People don't love each other anymore. This could be prevented if people really thought about how much they loved, who they were marrying and if they really want to spend forever with this person.
I think it is stress, lack of trust and respect, being underprepared for the future, early marriage, and getting married for irresponsible reasons (early pregnancy, etc.).
The other has a lover.
Not happy with the marriage anymore. Different raising strategies.
Fighting.
Adultery, abuse, "I don't love her/him anymore."
Money or cheating.
Cheating, too much arguing or just not working.
Parents not getting on.
Money issues, parents argue, parents don't love each other anymore.
Parents fall out of love, too many disagreements.
Cheating, lying, or money.
Disagreements.
Falling out of love, adultery, abuse.
Verbal or physical abuse, "fall out of love," infidelity.
Fighting, money problems.
I think that the usual reason for divorce is not getting to know the person you are marrying beforehand. Sure, you know some things about them, but have you really thought about what you are going to do with the family money, what issues you might face later, etc.?
Money, parents are retarded, people are stupid and marry people they don't love.
Money issues.
No love, children, job loss.
Parents don't get along.
Stress, falling out.
Disagreement.
Fighting.
Infidelity or incompatibility, I guess. I'm not sure.
I am no expert, however, I can tell you the main reason is that the marriage did not work out for some reason or another.
The usual reason for divorce is parents are in a rut in their relationship and it seems as though there is no way out of the rut, except for divorce.
Not loving.
Abuse and cheating are the most common that I have heard of.
Parents think other parent is bad influence for kid.
Unhappy.
Parental strife, "falling out of love," abuse.
Rushed into marriage.
Argue, cheating, can't get along.
"Not compatible."
Cheating, not getting along anymore, met someone else.
Well ... there are many reasons why dirvorces happen. It could be they don't love each other or the other partner has cheated or there is simply no trust. It is all different loads of reasons.
Disagreements.
Money or cheating.
They don't love each other any more.
Don't get along, too much fighting.
Money, parents can't agree and don't get along.
Sexual transgressions or money issues.
Parents don't get along, parents get sucked into media telling all about younger women/men, sex, money.
No reason.
Marrying early on in life when they don't understand themselves.
People giving up and not wanting to work on a marriage. It's easier to give up than it is to actually try.
The parents don't love each other the same way anymore, there were problems like an affair, abuse, or just different ideas that weren't compatible for a family situation.
Unhappiness, too young, can't support affairs.
Fighting.

Disagreements between parents, different lifestyles, different morals and moral obligations, different religions, people not meant for each other.
Parents have too many problems & seldom agree.
Infidelity, unresolved disputes, incompatibility, abuse.
Parents don't like each other.
The relationship just doesn't work out between the two people. Maybe one person gets abusive and the other person just doesn't want to stand it.
Infidelity, one spouse not being committed to the marriage, lack of communication.
Not getting along anymore, or maybe they just don't have the same feelings they had for each other before.
Not agreeing with your spouse, cheating.
Fighting, disagreeing, cheating.
Not getting along, cheating, uncertainty, stress, unable to handle the responsiblity.
Having never experienced a divorce firsthand, I can only speculate that the majority have financial issues somewhere near their root.
Maybe because they do not like each other. Or because they had an accidental pregnancy and do not wish to stay together after it.
Not happy, fight too much, etc.
Not getting along, affairs, "I don't love you anymore," the kids, it's not working out, etc. ...
Parents fighting, no problem solving between the couple, financial, cheating/adultery, unsafe conditions.
