Ten years, no fighting, no friction, and you're looking forward to telling a coworker first. That last part is the symptom. Nothing is broken. The two of you just stopped being where new things land.

The pattern: you run this house like a well-run project. Alternating chores, split money, fair division. Fair is great for a roommate. It is quiet death for a partnership, because nothing you do for each other is needed anymore. You never get to be generous when the schedule already covered it.

Three concrete things, in order.

1. One week of noticing, before the talk. Where does the good version of you show up now? If it is mostly with friends, that is your answer. You are fun with them because that time is unplanned and carries no shared logistics. You do not need a new person. You need unbooked time.

2. Say the true sentence to your spouse, not the polished one. Not "we should reconnect." Something like: "I miss being the person you tell things to first. I caught myself saving a story for someone else and it scared me." Specific, yours, and impossible to answer with "let's book a date."

3. Trade one planned ritual for an unplanned one. Not a better date night, a worse one. Do something neither of you is good at and has to figure out together. Shared novelty puts two people back in the same story. Being good at it was never the point.

The honest part: sometimes a lull is the relationship saying it is done growing. If you bring this and the other person will not move, that is information, not a failure you caused. But you have not said the true thing once yet. Do that before you decide anything.
