He doesn't believe in anxiety and depression in teens.
Lol.
For one thing, he has two sons ... Is that right?
Anxiety and depression is more common in females than males after puberty .... Because of the massive toll hormonal changes & cycles take on females. So he's an ignorant fool for not knowing that.
Even if it weren't a gender thing ..... Teens are humans, they are young adults ..... And since humans can get anxious and depressed, what is it about teens and their bodies and brains that makes him think they are some magical exception to the rule??
He sounds rather stupid, idiotic and wilfully blind.
Also so what his two sons are at uni and apparently didn't have any problems. A. they're male, b. They're them ..... People are all different, your dd is not a robot clone of other kids and vice versa. He was lucky his sons haven't suffered any mh problems, anxiety or depression, that's all
C. If typical parenting patterns are anything to go by, I bet their mother did most of the work and deserved most of the credit anyway. Did he have them 50-50 and take a totally equal role in their schooling, upbringing, support etc.? He'll say he did but did he really?
He's not a good person to have around you and your dd. He's foolish, ignorant, black and white, lacking compassion, hard-line, patronising etc.
He needs gotten ridnof. I'd not be having the dick of a man coming out with all this crap near me, let alone inside me; sorry to be crude but there it is.
