Philophobia (Greek φίλος filos, “beloved, loving" and φόβος phobos, "fear”) is the fear of being in love and falling in love. It is defined as the abnormal, persistent and unwarranted fear of falling in love. The risk is usually when a person has confronted any emotional turmoil relating to love in the past but also can be chronic phobia.
Sometimes a person dwells on bitter memories of past relationships that didn’t go well or that ended badly, whether romantic or familial. Or the sufferer may have an intense fear of rejection and avoids relationships as a way to avoid the embarrassment of being refused by a potential lover. Others may have gone through an acrimonious divorce and be convinced that falling in love again will only lead to another painful divorce or breakup.
