I must disagree, I think in this case breaking this off seems to be the hardest thing. Sometimes in life we have to learn that we need to let go of the "confort" I'm order to grow and find happiness. I think in their case, I hope they can have a serious conversation and maybe think of divorce, since to me it looks like they both found a better place elsewhere.
They are not at the point of no-return yet. There's still room for them to reconcile. If there weren't, they'd definitely, at the very least, think of divorce.
And about them finding a better place, they haven't, they are just deluding themselves with the idea that I've found my place. If they had their partner's attention then this better place would've been the one in which they were already living.
If someone wants the realistic kind of anxiety in this Corona, then this is the right place.
I love this series and I hate it too. It's wayyyyy too realistic. I really wanna see how the author will conclude this. I hope there's constructive drama in this than destructive.
I personally would like to see everyone patching up with their partners. Like breaking off is easy, but glueing together the broken pieces and still staying together, that's the hardest challenge. Redeeming characters are such a breeze and the forgiving ones are even greater. ┗( T﹏T )┛
