How do I stop overthinking in a relationship?

Notice the thought, write it down and ask whether you have real evidence or just a fear. Share worries calmly with your partner instead of testing them. Fill your day with things that are yours, such as friends, hobbies and exercise. If anxiety is constant, speaking with a counsellor can help.

Set a ten-minute "worry window" each day. When a thought comes at other times, note it and save it for later. Often you will find that many fears fade by then. Then ask your partner about one real concern directly instead of guessing.

You may be ready if you feel reasonably content alone, can talk about needs honestly, handle disappointment without blaming and are not looking for someone to fix you. Do not wait for perfection. Start slowly and be honest about where you are.
