Divorce- is it really worth it?

We talked a lot about many different things pertaining to divorce in class. One of the main things that we talked about was how it affected the children. The children are sometimes the ones that are hurt the worst as they are pitted against one parent or the other, they might have to decide which one they "love" more and choose to stay with, they might still have split up time, and further more- it wasn't even their fault, why are they the ones that are in the cross fire? It breaks my heart to see this, and yet divorce is all to prevalent in our society today.
Our book, "Marriage & Family: The Quest for Intimacy" by Robert H. Lauer and Jeanette C. Lauer (8th edition) states that there are 6 stations to divorce, they go as follows:

1- Emotional divorce: involves a loss of trust, respect, and affection for each other.
2- Legal divorce: when the court officially brings the marriage to an end.
3- Economic divorce: settlement of the property.
4- Co-parental divorce: occurs when the couple has children- decisions need to be made about custody, visitation rights, and continuing parental responsibilities.
5- Community divorce: the friends of the previous couple become "divorced" as well and are sometimes forced to choose sides.
6- Psychic divorce: the individual must accept the disruption of their relationship and regain a sense of being an individual rather than being in a marriage relationship.
*(All of these are directly from Lauer and Lauer's book "Marriage & Family: The Quest for Intimacy")

The main ones talked about were co-parental divorce, and community divorce. The co-parental divorce is as I mentioned previous- the children get caught in the cross fire. There are a lot of decisions that need approval from both parents and it can be difficult when things are hostile between the divorced adults. The child sometimes loses a sense of belonging and sometimes feels resentment and/or guilt about the divorce and is not sure how to deal with it.
With community divorce, it can be difficult for just about anyone that has known the couple. If a friends stays friends with one spouse, the other one may feel rejected, and sometimes a new group of friends is needed to somewhat heal the issues from the "community divorce".

I have seen divorce tear families apart, but I also know that there are situations that it is not good for the well being of the family to stay married. I believe that if both spouses are selfless and serve each other and are constantly trying to help the other person that the marriage can and probably will work out. It takes an effort every day to keep things together, but I know from my parent's marriage of 30 years, and having had 11 children that it can all work out if you keep the right things in perspective.
