You give an inch, she will take a mile. You got married to be with this person for life not to take mini breaks when the feeling hits her. Set your boundary: You can not be in a marriage where a third person is involved and stand firm. Tell her that you are sorry that she feels this way but this is not what marriage is about. You are not a safety net.

She may be 80% sure she will be back but I am 100% sure you would be gone.

Keep posting.
