The marriages you saw and experienced growing up were a mixture of good and bad. If your parents were happily married you saw many good things such as communication, respect, growth, commitment, and more, even though they were not perfect people. But marriage in the real world today is different from that of your parents or other healthy couples you observed.
Something is stressing you out. As hard as you try, your anxiety or depression seems to be eating you alive. You keep falling into the same sexual sin over and over again, and the shame seems too heavy to bear. Perhaps your marriage is simply miserable, and you see no way out. You need help, but it seems you can’t talk to anyone.
No human being escapes all suffering. While perhaps unkind, it would have been true for me to say over the baby I delivered today, “Welcome to a lifetime of suffering, little girl.” And Jesus promised that “in this world you will have trouble.” (John 16:33) But wouldn’t it be a good idea to escape unnecessary suffering?
Marriage is the union of two sinners. You can be sure your spouse will mess up; that’s what sinners do. And the same goes for you. Whether you knew better or not, you will fail your husband or wife in some way, perhaps in many ways. So what do you do if you messed up in your marriage?
