This last weekend, schizo-boy went to stay at his middle-brother's house. When he came back, he was even quieter than normal.
Today, he did not wake up until after 4 pm, which tells me that he is not sleeping at night.
Now I just got off the phone with the husband of his ex-girlfriend whom we had asked to contact us if schizo-boy attempted to contact her again. The husband, whom we'll call Fred, stated that they received an email today from schizo-boy.
So, now we are working through exactly what we are going to do about it.
