Lots of information needed so we can point to things that might make you help make your decisions.
How long have you been married? How many kids? Do you work? Does he? Are you needing alimony/child support?
Is he cheating? Beating you up? Drinking, gambling away the money? Are you bored, depressed, lonely?
Do you have family nearby who can help you talk through this? Have you had marital counseling?
For some people, divorce is the way to go, but for others, reconciliation is possible. There's not a chance we can let you know whether your concerns are the type that usually point to divorce or usually point to working things out, unless we have more information about your concerns.
