might be time for a new mother-in-law.
I think her husband should handle this matter. His silence of this issue is disturbing.
unless you are relying on your mother in law for camping supplies, i would personally call her on the telephone, or visit in person, and dis-invite her from the trip and do the same for the ex-fiancee.
It is my MIL's 5th wheel in a gated lake resort. Other campers are reasonably priced for rent with the owners invitation. These additional rentals are then placed next to hers. We will grill and be having meals together, campfire conversation, etc.
It was arranged a couple weeks ago for the Memorial Day weekend that I and my family spend the time there.
Playmates are not an issue. There is a lot for the kids to do. Fish, swim (pool & lake), pony rides, playgrounds, and more. At the end of the day they crash from all the activity.
This is not the first time this has happened. My husband doesn't see anything wrong with his mother doing things like this. He says she just likes everyone.
It's very offensive to me and I don't think it is just me. I wanted to see if other men shared his opinion that I am the one with a problem.

You have every right to be enraged. I would be absolutely furious. Your mother in law and your husband have no right to treat you with such disrespect.
