DBT skills for breakups?

Background: probably breaking up with my significant other (of >1yr)

I've done DBT (Dialectical Behavioural Therapy) and I KNOW there's a heap of good skills that I can be using whilst breaking up with someone, but I'm sure there's others I've forgotten. Can anyone with knowledge of DBT think of any skills that'd come in handy?

Skills I definitely plan on using:
- Mindfulness (so I can keep an eye on how I'm doing emotionally)
- Pros and cons (to work out whether to break up in the first place)
- PLEASE (for looking after myself generally throughout the process)
- DEAR MAN (for the actual break up conversation)
- Coping ahead (for having the conversation as well as dealing with the fallout)

Not sure how many people on here have done DBT, but thought I'd try here because whilst googling literally every article I found was about how to break up with someone with BPD, not the other way around 😕

Thanks all
