If it can be talked through in an atmosphere of love and acceptance, the resolution of the infidelity can lead to a stronger marriage. Infidelity is normal. Some people believe that because of today's longer life spans, it is appropriate to marry several times within one's lifetime. However, what is normal and healthy is to have good communication within our relationships and to provide a sense of protection, comfort, and security for our partner. Infidelity leads to just the opposite.
Men are more likely than women to have an extramarital affair.
This may be only somewhat true. What is important here is that a substantial proportion of women also engage in infidelity. Only troubled marriages will experience infidelity. Infidelity can be found in marriages, which are healthy in most respects. Despite a healthy marriage, one of the partners can slip.
