It's impossible to look at someone who is married and determine whether he or she will someday get divorced. However, you may fit certain category descriptions that researchers in Pennsylvania or elsewhere have classified as high-risk groups for divorce. It's logical to assume that the more issues you can relate to, the greater your chances are that you and your spouse will decide to go your separate ways at some point in the future.
If that happens, it's not as important why you chose to call it quits, as it is what type of support system you have to help you come to terms with the situation and move on in life. You'd likely feel relieved if you and your spouse can resolve all necessary issues and achieve a swift and amicable settlement. Things don't always go that way, however, so it's also good to have a plan of action in mind if a particular legal obstacle arises.
