RNP,

Use this as a lesson learned. Stop talking to your MIL about your H and anything that H has told you.

Blood is thicker than water and if you want to stay in your MIL good graces, and even if you don't, it is wise to zip your lip.

If you should reconcile with your H you don't want any issues that would pit you against your MIL, and force your H to choose between the two of you.

Use the utmost discretion with anything you say to MIL that involves your H and or them.
