Major Violation of Boundaries -- I am blindsided

The exhusband went over to the house I had under contract, and wandered around outside it with my kid, looked around, met a neighbor, etc.

OMG. I just found out. The lengths they go to! He's REMARRIED! He will not let go or leave me alone. He's got to get IN.

It's really the perfect violation. Because he can claim all this innocence, blah blah blah.

I won't say a word to him.

My kid didn't know that I had cancelled the contract.

I explained things to my child. Child is clear about boundaries and how completely not okay that was. Absolutely NO MORE OF THAT EVER.
