romance, met on beach vacation, get married, move, & then problems

[Shenanigan]

Not sure how old the book is but I read it within the past 6months or so. A man and a woman each on a solo beach vacation meet at breakfast(?), they spend their whole vacation with each other & get married or move in together(?) I think the guy is wealthy, maybe works in something bank related(?). He gets a promotion that requires him to live out of town during the week. His ex girlfriend works with him. They see less and less of each other then decide to try to have a baby. His mom doesn't like the wife and wants him back together with his ex girlfriend. Wife buys husband a painting of the beach they met on for their anniversary to hang above bed. His mom and ex are both very rude to wife and husband takes their side. Also, there was something about his mom not liking flowers on the table(?) I'm pretty sure he starts having an affair and idr if wife ever gets pregnant or how it ends.

Shenanigan, how old is the couple? What are their jobs/skills/interests?

What's the tone - e.g., romantic, angsty, steamy/clean, funny at times, sad/somber?

Where do they live (country/region/city/small town)?
