Don’t answer if this is too intrusive but why don’t you just have a joint chequing account for bills? It seems like a lot of married people split bills but don’t bother just having a dedicated account for it so you never have to think about it. I can’t speak for every bank but the one we use (TD) let us link a joint chequing to both our individual accounts so we have separate money/savings and then joint money/savings. Either of us can spend / deposit and it’s all handled in our personal logins.

For my wife and I it has a lot to do with her experience with her ex husband. He refused to let her access the account, and held her money hostage. Frequently didn’t pay the bills and spent all their money on stuff he couldn’t actually afford. He wouldn’t even let her have any food other than ramen and tap water. He would buy actual food for himself but kept it locked up so she couldn’t eat it and kept the key hidden. 

Based on that experience she says that she’ll never open a joint account with anyone again, and I can’t say that I blame her for that. We just cashapp each other for stuff.
