Well - I have been at my mom's house for 3 days now. H has texted a couple of times to ask how our daughter is doing - I have just responded with quick, but positive, texts back: "She is doing great - having fun playing with kitties and hanging out with gma and gpa". He hasn't pushed beyond that.
He is likely staying in our home while I'm gone - I haven't asked, but it wouldn't surprise me if he's run from his mom's house now that that is getting intense given my exposure. And, phone records show him texting with our neighbor, which likely means he's home. Not sure how I feel about this or how much I care - also not sure I can control it even if I do care. The positive would be that it has all the family memories he will be haunted by - the negative would be that he's not accountable there because no one knows what he's up to.
Though my neighbors would likely tell me if the girl appeared - they did tell me the time she stayed over at our house (which of course my husband still claims was harmless - "her brother was with her and they had to stay because their parents' house where brother still lives is being renovated and they didn't have beds". He did provide a picture to me of her in a under-construction living space, but I still doubt it was harmless . . .).
