Curious and Concerned

Hi, Please bare with me as I try to explain and ask my querie being curious and yet concerned... Is it fully within my right to know where my kids are, what environment they're in?, and who they are with??? In the last 3-4 weeks ive spoken to them maybe 3 times always seperate, and on loud speaker, I dont get msgs back as I normally would, and on top of that I know things I shouldn't know and thats what is the concern, people and environment I dont want my kids to know or be situated in those surroundings... Dunno if it matters but Im the one theyve always known as dad, until recently I assume when I had a brain fart and unknowingly woke the underworlds demons of darkness. Do and Should I mention something? Repercussions are a health risk..
