He cuts in before you finish. He has something to say and it comes out now. This is the Interrupting Pattern. Competing by speaking louder makes it worse. Stopping entirely makes it permanent. There is a middle way.
Practical Techniques
Reclaim Your Turn With a Short Phrase
Practice a few calm phrases. Say: “Let me finish this point.” Or: “I want to complete my thought first.” Say it once, calmly, then continue talking. Do not wait for permission.
If he cuts in again: “I notice I have not been able to finish. Let me wrap up.” Then continue.
Pause, Then Resume
When he cuts in, stop. Let him speak briefly. Then say: “As I was saying…” and pick up from where you were. A raised hand helps signal you are still mid-thought. Do not raise your voice. Raising your voice turns a habit into a contest.
Create a Structure for Big Conversations
For anything important, agree on a simple rule up front. Say: “Let’s each take a few minutes to share our view before we respond.” A timer works. So does a talking object. What matters is that both of you agreed before the conversation started.
Why This Works
Interruptions feel personal. These techniques keep them structural. You are not accusing him of dominating. You are managing the flow. That is easier for him to accept.
If the Pattern Continues
A repeating pattern needs a direct conversation. Not in the moment. Later, when things are calm. Say: “I notice I rarely get to finish my thoughts when we talk. Can we work on that?”
