Books that believe in marriage & are funny

I’m looking for books that are marriage-affirming (centers a marriage that the author believes in) and that are funny / light / charming. I’d still like it to be well-written literary fiction, but fun and not dense.

Here are some examples of books I’ve loved that I think fall into this category:
– Standard Deviation by Katherine Heiny
– What Alice Forgot by Liane Moriarty
– The Husbands by Holly Gramazio

Thanks!!
