How to help my boyfriend

I have a boyfriend with BPD and that is absolutely not a problem, I just feel like I’m not helping as much as I can be. He dissociates a lot, and spirals and every time I talk him through it, I ask him to tell me about his favorite bands, I make him do the “tell me 5 soft things you see”, I help him take deep breaths, but I’m always scared this isn’t enough. I do not want to break up with him, I love him so much, I just want to know I can adequately help him and be there when he needs me.
