Ines Good idea for a story...
Yes,I think it can be a great story too!
Angelina unfaithfulness begins even before sex, if a woman or a man does not want to have their own spouse anymore, it is enough to think or act in this direction
Yes,but,as long as he/she doesn't have sex with someone else,if he/she has no romantic time with him/her,it is easier to save his/her marriage,I think.
However,if he/she gives him/her pleasure(and even if there is no orgasm for him/her),or spends a lot of romantic times with him/her,even without anything sexual,I think too it would be hard to not divorce.

It would be easier if we know a bit the written situations you have,even if it would spoil the story...
