To be in a successful and happy relationship with a commitment phobe, you are going to have to sit through their entire life and assure them that now—the present—is different.That they can be part of a healthy, enjoyable relationship even if they commit.
You are expecting an openness between the two of you, without hesitation.
In the world of dating a commitment phobe, this is not going to happen.
They will not get close to people you care about because they do not want to be questioned when the relationship is over.
So when you are out with your friends, it is most likely that your partner is not going to join you. You will never be able to understand or predict what they want.
They might be sad, unhappy, and upset about something, but they will most likely push you away if you try to help.
While you may understand what they want, they themselves are not quite sure of what they want from the relationship or life in general.
They are always thinking if they are going to be able to do it without backing out at the last minute.
You are going to be hanging in the balance of uncertainty.
Even worse, you will not always be able to directly blame them for it because sometimes the excuses that they present to you for not being able to commit seem reasonable.
