Why arguments feel so different to each of you
The same conversation lands in two completely different bodies. For one of you, conflict feels like the ground opening up — proof that the relationship might end. For the other, it feels like an unbearable pressure cooker that you have to escape, right now, by any means necessary. Neither of you is overreacting.
What attachment does to conflict
Attachment style shapes the entire conflict experience: how fast you escalate, what you reach for (pursuit, withdrawal, fixing, freezing), what you need to feel safe again, and how long it takes you to come back online after a rupture. Most "communication problems" are actually attachment systems doing their jobs.
