Commitmentphobia is often most strongly apparent in romantic life. Generally, commitmentphobic people claim that they are eager to find a lasting romantic attachment and get married, yet they fail to find appropriate partners and maintain longlasting connections. Ironically, in these romantic relationships, the commitmentphobic partner craves what he/she fears most: love and connection. This paradoxical craving for a frightening reality leads to a confusing and destructive pattern of seduction and rejection. The results are emotionally devastating.

The key to understanding commitmentphobia is recognizing that such behavior is rooted in fear—fear of lost options or fear of making poor decisions. The commitmentphobic mind sees decisions as permanent, opening the possibility of being caged or trapped forever with no means of escape. Commitmentphobia is a real disabling fear, that can be manifest in many areas of life, including career, home ownership, or even shoe shopping. This fear can make simple every day decisions into a tremendous burden.

To assuage their anxieties, many commitmentphobics become fantasy-driven, using their active imaginations to fill in for the lack of emotional security and closeness in their lives. Of course, these fantasies pose additional problems because no potential partner or job can ever live up to the fantasy. Commitmentphobics are also prone to self-destructive behavior, such as walking out on partners or jobs without notice, leaving themselves and the people in their lives in untenable situations.
