Maybell, sorry to have to hear this dumb gossip. I love the horoscope! How funny.
Try not to let it get to you too much. I would echo what others said: let him go on his own dumb path. It's the only way for him to learn, to go through whatever he is going through, and maybe he will come out the other side a better person with more sense. Let's hope. I hope the same for my wacky WAH who used to be the most admirable person I knew and is now behaving like people he laughed at - exactly as you said.
I wish you a wonderful rest of the day! Hugs, Lisa
