Just found out ds7 has been on laptop at midnight whilst at xh. Last week it was at 1 20am! He shuts down any conversations so usually converse over text but has ignored previous conversations. He bought the laptop so I can't really keep it here when he goes to his dad's ( was supposedly bought to help with homework). He will probably tell ds to ask me why I am checking browsing history) WIBU to install Microsoft software to set time limits ( I know this will cause animosity btw). Or any other ideas?
