Agree what support looks like
- Ask what helps when emotions first start to rise.
- Record professional and urgent contacts.
- Agree what information can be shared and with whom.
- Choose a small number of responses you can give consistently.
- Review the plan after a difficult period, without blame.

Make boundaries specific
State what you will do and when. A boundary is not a punishment or an attempt to control another adult. It explains the conditions under which you can stay involved safely and reliably.
“I can talk for half an hour after work. I cannot answer calls through the night. If you are unsafe, we will use the urgent contacts in the plan.”
Avoid becoming the whole support system
Notice if you are cancelling your life, monitoring constantly or becoming the only person they contact in distress. This is a sign to widen the plan, not proof that you should try harder alone. Include professional contacts, other trusted people and support that belongs to you.
Review patterns without turning them into blame
In a calmer period, choose one repeated situation and write down the early trigger, what each person noticed, what escalated it and one response to try next time. Keep the plan short enough to use. If the relationship includes fear, coercion or abuse, prioritise your safety rather than treating it as a shared communication exercise.
Keep the relationship wider than the diagnosis
Continue ordinary activities and interests where possible. Do not treat every feeling, preference or disagreement as a symptom of BPD or EUPD.
