Imagine you are in a marriage that is slowly but surly crumbling. To avoid divorce, the two of you come to the mutual decision to separate. While being separated, one of you decides maybe it is a good idea to court, casually known as dating. Technically by law the two of you are still married and in theory it is indeed cheating. However, emotionally and mentally your spouse needs a "breath of fresh air." But really, what effect does this have on everyone involved?
Some may argue that what the other spouse doesn't know wont hurt them. On the other hand, what about the "outsider" who is being dated?Statistically speaking, only 20 percent of men leave their spouse for the "mistress." So where does that leave the other person? Probably in dismay about what has taken place. They've become accustomed to a temporary companionship. Imagine how much emotional damage was done. Two people have developed a bond, spent time together, shared emotions, and everything that comes with a relationship, just for it to be thrown away.
In all honesty I don't believe couples who are separated should date. The purpose of a separation is to regroup and refocus on how to fix the marriage; not go out and find a boyfriend or girlfriend while still legally being married. There are so many factors involved in a separation. Not only are the spouses effected, but the people around them as well.
