My partner lies about reservation times because I am always late, and I hate that the trick works

For our anniversary dinner, my partner told me the reservation was at seven. I was ready at 6:52, which counts as unusually early in my personal history.

When we arrived at the restaurant, the host said our table would be ready at 7:30. I assumed the restaurant was behind. My partner admitted the reservation had always been at 7:30.

She has been giving me false start times for almost a year.

At first I was angry. Then she opened her calendar and showed me the entries. Her sister’s graduation said 8:30 even though it began at nine. A friend’s dinner said six instead of 6:45. The airport pickup said 3:15 when the flight landed at four.

The humiliating part is that the system worked. We were on time for all of them.

I do have a lateness problem. I underestimate every transition. I think a shower takes ten minutes because ten minutes is how long the water runs, not how long it takes to find clothes, feed the dog and locate my wallet. If we need to leave at six, I begin one final task at 5:48 with complete faith in a version of time nobody else experiences.

My partner used to remind me. That led to arguments where she became my supervisor and I became a teenager defending why my shoes were not on. Eventually she stopped arguing and changed the information.

She calls it padding. I call it lying, although that word sounds dramatic when the result is arriving calmly instead of apologizing at the door.

What bothers me is that I no longer know whether a stated time is real. Last Saturday she said we had to leave by ten. I was ready at 9:45 and then spent twenty minutes wondering whether she had invented the deadline. When I asked, she refused to tell me because, in her words, ‘Then the system collapses.’

That made me feel managed rather than partnered. It also made her cry. She said being partnered with me has meant standing in coats while I answer one more email, texting hosts that traffic is bad when we have not left and absorbing the embarrassment when we arrive after food is served. The false times are the first solution that did not require her to fight with me.

She is right that my behavior created the problem. I am still uneasy with a solution that depends on me not knowing reality.

I offered to manage departure alarms myself. She said she wants to believe me but does not want to be late for everyone’s events while I prove I can change.

How do we retire a dishonest system that compensates for my unreliable one? Is it reasonable for her to keep using padded times until I build a track record, or does the fix need to work even after I know how it works?
