Hi cookiecookie,
First, I'd say that going through DBT is a good thing to do. Many hurt members here will say that it doesn't help, but the studies don't support this.
Just as we encourage members not to paint all pwBPD with the same brush by assuming "x traits=y behaviors" it applies to those without BPD as well. That being said, it's not wrong to try to understand another's point of view.
This board is set up to support those with people with BPD (pwBPD) in their lives. As such, resources and support for you may be better found here:
