So recently I posted about DD21 (who has autism and acts more 16/17) seeming like she was sneaking around and me not being able to do anything about it. Her best (male) friend spent the night 2 weeks ago and after she left for work him and I got to talking and an old friend of hers was bought up and he seemed really surprised I hadn't heard about a big fight between them and told me he couldn't say anything more. Well today I reactivated my facebook and saw my DD and this girl aren't friends and asked her why and she goes 'no reason' and I explained that (name) had said they had a fight. DD told me nope; and continued about her buisness. 45 minutes later she snuck onto my computer to see this girls profile, and my younger kids ran to me and told me she was on my computer, I shoved her away before she could close it and saw the girls profile. I yelled at my DD for lying to me, I deleted the other girl so that this innappropriate behaviour of stalking her (DD has that habit) could not continue and I (as we have guests for a week) have written an email to my daughter expressing my disappointment in her lies. My question is should I force her to talk about it or punish her or what? she's spent the rest of the day hiding in her room with her laptop and won't let anyone near it.
