Please. Change the locks. Don't give him a key. It's about recommitting, and really meaning it.

My suggestion: change the locks again. If he is not living there, he doesn't need to be snooping around. He can't have a key until he agrees to MC and to drop the OW permanently.

And get a new lawyer.

Im still standin better than I ever did looking like a true survivor feeling like a little kid Im still standin after all this time and Im picking up the pieces of my life without you on my mind..
