Your situation definitely calls for a controlled separation.
Give her the space she needs and don't pester her.
But make sure you both understand this is a 6 month break to sort it out, not an excuse to go out and date and sleep with others.
I know you said you did your homework and you're sure there's no one else but how can you be 100% sure? In cases like this there is usually someone else. Sometimes cheaters can be very good at covering their tracks, especially if they know they're being watched.
