Do you know someone with borderline personality disorder?

Hannah • Fur mamma. Heathen.
Hi there. I have bpd and my boyfriend is very supportive and I have been doing dbtherapy. This disorder has been very hard on our relationship. But I have been trying to control my emotions and have been reading up on dbt. But even still there are days when my boyfriend feels like he's walking on eggshells. I was just wondering if anyone knows of any books or online resources that would be beneficial to him? Or have any suggestions or tips for loved ones of those with bpd?
