Since my last post, me and dh have been attending marriage counselling to try to sort out our differences. Turns out dh didn't tell  ss15 and sd14 that I wanted to send ss13 to boarding school. Dh was talking to his brother  and ss15 overheard. Ss15 told sd14, who then asked dh if it was true. Dh told them not to worry themselves about it, it's between dh and I, but they still ending up telling ss13, and the sd14 told my MIL who then told the whole family. Dh did apologize for letting it get out of hand.
