Hi Lanzo, Could the way she's been acting lately be a result of the stress of living in a house that's in upheaval? Sometimes I lash out at things that are petty when I'm feeling particularly stressed. If there's alot of stress, I don't have the energy to stop and think before blurting out something that I wish I hadn't said. Not a good trait, but I've been working on it.
I would suggest doing something particularly nice for your w to show her you love her and will continue to love her, even if the alien swoops in every now and then.
