Yep. Abandonment.
She won’t get anything in the divorce either. She’ll be left with the clothes on her back. Nothing more.
You would be amazed how well she could come out of this in Florida. First of all, she will get some kind of joint custody. Next up will come the distribution of the assets, no matter what she did, divorce here is no fault. The hubby may even end up having to pay a support stipend.
He needs to pray she never returns and in fact, just disappears.
