What do you think about this situation?

A married couple is getting a divorce. This married couple are Christians and there was a affair one one of them parts. The other found out. But they keep having sex until the day they divorce. But they are still getting a divorce no matter what.

I am not saying that this couple is in sin. But what do you think of this?

Now before someone tells me no I know this isn't any of my business I am asking hypothetically but I know that it does happen sometimes. But say even though they are in the process of a divorce they keep having sex during that process and once they are officially divorced they are no longer going to be having sex. Then they are going to move on and try and find someone else and won't' have sex until married
