I agree with you. Also, it's questionable whether or not their relationship was open to begin with. Lingerie parties at the house?
I personally think if Lenny wants her back, she will go back. Lisa already said she didn't care about his "emotional" cheating back in the day. Did anyone ever read Morgan O's take on their affair? She wrote a
blog post, never directly naming him but it was obvious it was about Lenny.
There's some drama going on Reddit claiming one of Lennys friends is accusing Katharina of cheating on him.
