A commitment phobe has a real fear of making a commitment and is common to both men and women although there are higher perceived instances of the disorder in men.
It is quite common to use the title incorrectly by applying to men who just refuse to commit because they are not ready to or just don't want to.
This is an entirely different scenario and should be treated as such.
In this article we will cover some aspects of commitment phobia.
A commitment phobe will have you convinced that he does indeed want to get married but as soon as your relationship grows closer he does things to push you away.
He may have a history of relationships like yours that ended suddenly for no apparent reason and he leaves a trail of devastation behind him.
The commitment phobic male views commitment as a loss of freedom with no chance to escape.
The behavior itself can extend beyond a romantic relationship too but it is only really apparent in the relationship.
Signs Of  Commitment Phobia

• A history of short relationships that ends for no reason.
  
• Pursuit of unattainable partners.
  
• They pursue you aggressively in the beginning of the relationship and might even raise the idea of marriage early on.
  
• They will do things to sabotage the relationship forcing you to walk away, including being unfaithful or disappearing for days on end.
  
• They act like you don't matter to them and promise to change when you threaten to leave.
  
• They may not acknowledge you as their partner to friends and family and find excuses not to meet yours.
  
• They have a history of short term jobs and platonic relationships.
  
• They exclude you from all aspects of their lives.
  
• They cut you off whenever you raise the topic about the status of your relationship.
  
• They make excuses to avoid spending time with you.
  

If you find yourself in a relationship with a commitment phobe it does not mean that you should walk away.
Like all relationships it needs work, only in your case it may take a little bit extra work and it is up to you to decide if your partner is worth it.
If you decide to stay you will need you to:

• First determine if he sincerely wants to change.
  
• Help him seek counseling in some cases.
  
• Give him the space until he recognizes that you are his "safe place.
  "
• Recognize that this is no fault of yours and not feel rejected by his actions.
  
• Hold him accountable for his actions towards you.
  
• Ensure that all your actions are to help him get over his fear and not motivated by your desire to bring him to the altar.
  Make sure he knows this.
  
• Be willing to leave if you have tried your best and it still didn't work out.
  

With time, patience and knowledge you may be able to help the most important person in your life overcome a fear of commitment.
