okay please tell me if im in the wrong or not but my husband mom only been in our life for a month after we kept away for her for a year after she started a bunch of shit drama so she randomly shows up when I had my daughter I allowed her to be there cause she said sorry and so on and I felt bad but now she's being a smartass and saying she's coming over didn't ask just commands things like she's been there through everything? so I told her it's rude coming over without asking and making plans.... now I'm the bad guy?
