Philophobia is the fear of falling in love. Not included in the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders). The risk is usually when a person has confronted any emotional turmoil relating to love but also can be a chronic phobia.

This affects the quality of life and pushes a person away from commitment. A negative aspect of this fear of being in love or falling in love is that it keeps a person in solitude. It can also evolve out of religious and cultural beliefs that prohibit love. It represents certain guilt and frustration towards the reaction coming from inside.
