What is the average length of a BPD relationship?

The average length of a BPD relationship is 2.5-5 years. However, this number varies as some studies have shown that the average length is about 7 years. At the same time, there are numerous case studies showing BPD relationships lasting for decades.

The reason why there is no set number for the average length of a BPD relationship is because everyone poses different symptoms at different levels of intensity. This can lead to varying circumstances in the relationship and can cause each one to have a different length.

Stages of BPD relationship cycle

Those who have BPD and start a relationship with someone often go through a relationship cycle. The different stages of a BPD relationship cycle have been described in the following section.

Stage of Idealization

This is the first stage of a relationship with someone who has Borderline Personality Disorder. In this stage of the relationship, the person will often idealize their partner as the perfect person and may seem them as being completely faultless

In this stage of the relationship, the person may do grand gestures and seem like they are ready to fully commit themselves already. Those who are close to them will find that they are obsessed with the newfound love and may see them doing impulsive things.

Stage of Insecurity

The next stage in the BPD relationship is where the trouble begins. In this stage, the person may start showing signs of insecurity over the relationship. They may often suspect that their partner does not love them truly.

They may also grow increasingly fearful that their partner is getting ready to leave them or abandon them, especially if they have criticized them about something. The partner may not realize this since the communication might not be too open at this point.

Stage of Anxiety

After the stage of insecurity, the person becomes convinced that their partner is going to leave them and develops anxiety as a result. They may voluntarily put distance between them and their partners.

This is often done not because the person really wants to end the relationship, but because they want their partner to prove their love for them. In this stage, they may want the partner to openly prove their feelings with some gesture or action.

Stage of Conflict

In this stage of the BPD relationship, the person may bring up many conflicts with their partner. There may be frequent fights between the two people, some of which can be very explosive and physically violent.

Stage of Ending

After a while, the partner may eventually emotionally tire out and may voluntarily step out of the relationship. In this stage of ending, the person with BPD may apologize repeatedly and may bring up grand gestures, making promises that they will not repeat their behaviors.

Post break-up stage

In the event that the partner does not come back, the person with BPD will find it hard to move on and may indulge in self-harming behaviors. They may loathe themselves, blaming them for everything that has transpired in the relationship.

BPD can lead the person to believe that nobody truly loves them for real and everyone will abandon them someday or the other. When a relationship ends, this thought gets drilled deeper into the person’s mind further strengthening their false belief.
