Commitment phobia is the unrealistic fear of making a promise or a vow to be faithful and loyal to another person. It is a common misconception that committing to someone means losing independence. Many people perceive being single as being safe and comfortable, which can be hard to give up. The ‘scary’ parts of being in a relationship, such as revealing your weaknesses and vulnerabilities, is what keeps people with commitment phobia from getting deeper in a serious commitment.
