Should my wife start dating other men while we are still liv

My wife told me two months ago that she was thinking of separating. Three weeks ago, she made this official. We must still live in the same house for at least three months. However, she has been flirting online for at least a month and has men that she would like to start dating immediately. She says it's not my business. It is so hurtful. Thoughts?
