I think your family lawyer friend is giving you good advice. If your wife is moving out to an apartment, that’s fine and is her choice. You just keep the home as you have been paying for it.

I don’t recommend taking a punish her mindset, that isn’t your style and will only serve to
Give her fuel to play the victim. Just plan on letting her go do her thing but do so wisely. You don’t want to act on emotions.

You need to realize you were in love with the fantasy and all you did was prolong your suffering and spiraled into depression and a very unhealthy mindset. There was never anything you could do to fix her. She wants out and to be independent, let her go do that for herself. You don’t have to be vindictive, yet you do deserve to protect your own interests.

Taking the vindictive path can end up with total loss and the lawyers getting whatever you have gained financially.
