Does the husband bullet journal, or something like it? Because there are (I think) two fundamental approaches to journaling. The common approach is to write down the important parts of each day (or, you know, whenever). The other approach is to write down related things together, which is the force that drives bullet journaling.

I suspect that LW might have thought less of the thing if she had stumbled into a single journal entry about the important events of the day. Or if there were other lists, like Big Questions About The Universe, wardrobe thoughts, work topics, lists for hobbies, lists involving other people.

The question is, is this a person carrying out a methodical approach to marital disagreements (like other things in their life), or is it someone bearing grudges and planning a steamroller approach to disagreement? Does he bring up things that you thought were long resolved with fresh annoyance/anger/frustration?

If he doesn't seem like the kind of person who uses your insecurities as clubs to emotionally wallop you, do you feel emotionally safe telling him that you've always been insecure about Topic A? (The distinction between unsafety and vulnerability can be hard to find in some cases. Do not be vulnerable in front of him if you feel it is unsafe. And if you feel it is unsafe, marriage counseling is not a good route. Individual counseling is often a good route in any case!)
