I love Ayn Rand’s literature, but I do not believe that her theories of objectivism really apply to Catholicism…just really economics.
You have a duty to address the situation immediately. Employ the help of your Priest or a Catholic counselor in the situation.
Has he always been like this? How are you both? Did something happen in his life that would cause this recently?
Do you have a degree you can put to use? Maybe he wants to be a stay-at-home dad? Or is he absent from childrearing as well?
There are a lot of unanswered questions that could completely change the sort of answer I would provide.
Assuming that he is just not living up to his “potential” I would show him how low the checkbook is, and ask him how he feels about not providing for his children. This is a bad market, but it isn’t that bad. Depending what his degree is in, he should be able to find a job.
As for the NFP dispute, I would remind him what the Catholic Church calls married couples to do. We are to abstain from the use of artificial birth control. It does not seem as though now is the time to be trying to conceive, and please remind him of that. How are you to have more children when he cannot provide for 6?
Also, pray pray pray! God shows us his love and gives us opportunities in those moments when we come to him. Also, does your husband pray and attend Church? Maybe he needs to regain hold of his faith…
Good luck to you. I can’t imagine how hard this is.
I’ve never been to Retrouvaille, but you may look into it. A number of people on these boards have seen the benefits of the program.
