Don't include me as being against IC. A lot of times it is appropriate, and is necessary to clean up severe personality disorders, depression, etc in order to be able to work on your marriage.

But when there is not a serious personality disorder, drug addiction, alcohol problems, chronic depression, IC is not necessary as a prerequisite to start working on your marriage. Depending upon the therapy and therapist, it may be at odds with the marriage counseling or individual efforts.

Each case is different. Use some common sense, and see if it serves your marriage and individual problems, or not.
