Hi Lookingforsupport,
Welcome and hello

There are specific tools (communication, validation, boundaries, timeout) that everyone in a relationship with a person suffering from borderline personality disorder needs to master.
People with this disorder tend to perceive the world differently than you and I, but there is an order and the rationale within that perception - it's not just random craziness as we might sometimes think.
Senior members on this board are very good at helping apply these principles to everyday life problems. The educational material to the right ----------> is based on the work from leading experts in the disorder.
The tools are not intuitive -- many have to be learned. Our BPD loved ones tend to be unskilled and bring the skill level down in the relationship. Our work is about raising the skill level and stabilizing the relationship.
How are things with your wife at the moment? Are there kids involved?
When your wife gets angry/rages, how do you cope?
Glad you found the site.
