First let me say that I'm well pleased with how Clark fully discloses, as best as he is able to, what happened to Lucy. This is not a time for secrecy even if it does feel protective.
Second I feel like Clark is set up. If he has sex with his wife he is hurting her. If he does not he is "rejecting her" because she is "soiled," if I can use the same twisted logic that Lois does.
Hopefully she will start to see this clearly. However, she has had a skewed vision for months. I doubt it will clear under stress.
That means that it is going to continue to get worse before it gets better.
