Is it too late to unsend those funds? It might make more sense to hold them back until he’s out of the house because my guess is he will just use them to binge and then claim he has no money to move.
I don’t know what your rights are legally... I don’t know if you have to file for divorce here or if you can there. Have you talked to an attorney?
I’m really sorry you’re going through this. Sending you a hug.
