Marriage trouble or relationship trouble with NO Cheating!

Ok! For so long I have searching for this trope where marriage is troubled because of what so ever reason with exception of the reason: cheating, physical and emotional both. I am literally fine with any kind of drama: some lame OM/OW misunderstanding, kids, miscarriages, workaholic partners, or just anything. Like I am sick of reading the novels where the couple breaks because the MC was unfaithful, it is not only reason why people break up. There can be much more.

However, please consider that it specifically should NOT have:

•Love triangles (you know where MC is constantly confused between two characters)

•As I repeatedly mentioned no cheating, physical or emotional.

•Tragic endings. HEA is must.

• Physical intimacy with other partners, if separation follows. (I am fine with dating.) Celibacy would be appreciated.

I know it's a lot, given the request is marriage trouble. But please help me 🤗

It doesn't have to be only marriage. It could be two people trying keep up their relationship (the stage where they are only boyfriend and girlfriend) intact despite the hurdles they face. I am open to both contemporary or historical romance.

If anyone is interested in similar theme then here is a very short list:

• the unwanted wife by Natasha Anders (the hero grovels until the last chapter)

• Something worth saving (it fits the bill perfectly, they been married for 8 years and are together for (15 years?) But the hero becomes ignorant somewhere in the journey)

• Nothing but this by Natasha Anders (>!the guy thinks his wife is cheating on him!<)

• lady Isabella's scandalous marriage (I didn't finish it for some reason I don't remember but I think it was good and it's historical)

• Just the way you are ( it doesn't fit my bill at all. >!The guy was forever confused, and it took him the whole book to decide. Emotional cheating? Yes. Physical? He kissed the other girl when they were separated!< . But I recommended it, if in case somebody wants to read it)

• After I do ( DNF, consensual cheating (?) )

Thank you,

Have good day/night ahead.
