You haven't been married long, he has not worked the entire time. What he wants and
what he gets are two different things.
My 1st ex, of 17 years wanted alimony, he didn't get. The court ruled in my favor. As for the deadbeat you are married to, anything he would get would be short term.
He has been using you for your entire married life, how long do you intend to continue your enabling? The longer you stay with him, the more it will cost you.
You did not set him up for failure, however, you have enabled him to the point that he
has a real sense of entitlement.
Take back your power, stop the insanity, sit down with an attorney and do what you have to do to regain your life, to have a sound financial future and peace.
