Probably not. A temporary separation may be useful as a way of motivating your spouse to deal with his problem, but it’s impossible to say for sure without more detailed information about your circumstances. But even with additional details, we still wouldn’t be in a position to tell you whether you have legitimate grounds for divorce or not. These are questions that you need to sort out with a trained Christian counselor.
You’re correct, of course, to point out that Jesus equates lust in the heart with the act of adultery. He plainly says that the one is tantamount to the other, and He does follow this up, just five verses later, by making allowances for divorce in cases where porneia or extra-marital sexual activity has invaded a marriage relationship. But you have to remember that Jesus, in this passage of the Sermon on the Mount, is speaking primarily in spiritual terms. He’s talking about our accountability in the eyes of God. He’s attempting to show pharisaical legalists that the literal keeping of the law will not necessarily justify them, since, from heaven’s perspective, it’s the condition of the heart that matters.
It’s perfectly appropriate to examine ourselves in light of this heavenly perspective. But we can run into problems if we start judging other people according to this standard or try to make it the basis of a social or legal code. You can see this very clearly if you apply the logic of your question to Christ’s statements about murder in Matthew 5:21 and 22. It’s absolutely true that murder begins in the heart and that all of us who think hurtful thoughts about our neighbors are guilty in the eyes of God. But does this mean that we ought to arrest people for getting angry? Should we lock them up, put them on Death Row, and even execute them for calling each other “You fool!” or “You worthless, good-for-nothing!”? Clearly not. The same observation applies to the subject of using heart-lust and porn addiction as “legitimate grounds for divorce.”
But enough of this theological talk. If your spouse is really addicted to pornography, and if your marriage is in as much trouble as your question seems to suggest, you need to find some serious help right away. The first step is to realize that sexual addictions of all kinds are strikingly pervasive in contemporary society. Because it is rooted in the basic human craving for relationship, sexual addiction is tenacious and progressive in nature. To put it another way, porn is powerful primarily because it offers a counterfeit form of intimacy and attachment. It’s important to keep these things in mind when seeking to help a loved one who has fallen prey to the deception that de-personalized sex can ultimately satisfy the longings of the human heart.
Instead of jumping to the conclusion that it’s time to get a divorce, we want to encourage you to hold on to hope. Effective help is available. We suggest that you and your spouse begin by seeking professional counseling, and we highly recommend that you do this together. The most successful course of treatment takes a family systems approach that involves an initial program of intensive therapy, followed by regular and ongoing counseling sessions. Also key to recovery is identifying a trusted friend or group of individuals who will provide an environment of support and accountability. Our staff would be happy to provide you with referrals to these types of programs or a list of qualified therapists in your area who specialize in treating sexual addictions. Don’t hesitate to contact our Counseling department.
