I think the problem has two faces:
1. Lois -being Lois- focussed on her job instead of share her life and problems with his husband
2. Clark being a naive by believing he could survive without Lois and that she could find happiness with another man's child..

En resumidas cuentas: son un par de cabezones!!!
In resume: What a pair of Lunkheads!!


Clark: "So what are you saying? I should go crawling back on my hands and knees?"
Martha: "No, honey. Fly back. It's faster!!"
