it's funny, I haven't read through all the responses here but honestly this, just happened to me. It's annoying af.

Thing is my (wife/ex/something) and I were separated for 4+ years with her having left us to another state for that amount of time, and only lives with us because she decided to come to be "close to her kids" and had no other place to go. I am weak and I let her come stay with us... but sorry to go into the detail but I thought it was relevant since she happened to "let me know" that her (my step) son and his gf and kids are coming for thanksgiving. Not asking, nothing like that. Just "oh hey... they are coming " kind of thing.

Aggravating as hell. It's not even as if I would say no but the courtesy to acknowledge that I am the owner of the lease, I care for everything and everyone... is asking me permission too much to ask?

Anyway... just so you know, you're not alone, I understand better than you think I do.
