Whether he loves his new apartment too much to want to come back and repair his marriage...
You can influence that by being a source of anger and shame or guilt and focusing on him and what he's doing and how he's affecting you, making it PAINFUL for him to be around you,
but other than that it's completely out of your control.
Let him figure his head out, give him space, and work on yourself, taking care of yourself, pushing yourself to learn and grow from this experience, ridding yourself of any bad habits you developed that you'd like to change going forward. A crisis can be a great spark for real positive change. Take advantage of it.
You can't make him want to come back but you can make him want to stay away. Focus on YOU.
