Sorry to hear about your latest update. You absolutely can work this out on your own and save on lawyer fees but you do need 2 lawyers. As I posted earlier I would have your lawyer draw something up in your favor and see if the guilt may get her to sign it. As far as housing you’ll need to see if your qualify for a mortgage on your own. Any chance you buy her out of the home? Telling your son will be difficult but children are resilient and he will be ok as long as he knows both parents love him. You are going to cycle through lots of emotions so try not to act on any of them. In time you will be just fine.
