This little jealousy act is just what this comic needed, I wrote on another forum about the relationship between Lana and Daniel and how he needs a bit of freedom to be able to fuck Sofia, Martha and the others, because now he only has his mom on his mind (look how even while massaging Sofia he is thinking about Lana) and that's admirable and lovely and I'm sure Lana likes that about him, but at this rate they will waste all those milfs just to keep him "faithful to Lana", at some point he has to fuck them and after 7 issues of pure mom/son, I think it's time to start.
I love seeing Lana jealous because she needs to understand that if she doesn't reciprocate Daniel's love she may lose him to one of her friends, right now Lana and Daniel are stuck in a loop (the scenes are getting repetitive) so I think the use of her husband in the plot, even if it's just to "punish" Daniel, may be a good thing because it will push Daniel to the other love interests, meanwhile Lana will be stuck again but this time to her boring husband, she will notice once again that he can't satisfy her sexually but also that he simply doesn't care about her, boosting her relationship with Daniel.
So, as much as it pains me to say, Lana and Daniel need a small break from each other, Daniel fucking the other milfs will give this comic variety and give Lana a more active role in future scenes with Daniel, because she will try to get her son/lover back with more intense sex and... who knows... if she somehow spies on her son fucking her friends and likes it, she may end up more open to share him in a future.
