Is My Son Being Manipulative?

Six years after Vali's first husband died, she met a man and fell in love. Her son seemed fine with the idea...until he wasn't. Vali wanted to know if his anger was manipulation. My reply? Maybe. It's common for major family transitions like a wedding to resurrect grief in kids so this mom should at least slow down, listen to her son and moved toward him emotionally. He needs reassurance. But is he manipulative? If he has a history than maybe. Either way, he needs a little TLC.
