My son was physically abusive to me as a teen and early 20s. He lived with my Mum from 16-18, then on his own for a year, then came back home. Huge mistake at the time, but... He couldn't appreciate me more now.
Do you think that by showing him this, that you will just reinforce to him, how negatively you feel about him and how you almost assume the worst.
Could his problem with women, life, mental health all stem from a broken relationship with you, his mother.
You can't help him by piling on more negativity. He's still young. I believe suspect at his age, he still can't fully engage with counselling because it's difficult for anyone let alone a teen who doesn't know how to open up.
I haven't read the full thread and I don't understand about the day back thing.
I think if you are honest with yourself, you have to admit mistakes were made on your part. I did. I was a young Mum, a single Mum, but was I always present for him when he needed me the most? No. It's hard to admit the problems stemmed from his Dad ditching and I didn't engage about that.
Don't forget there's so much bravado as a teen. He's not going to cry and admit he wants to feel loved, or something he's not getting. It's easier to act hard, talk shit.
I think it would be a terrible idea to bribe him to watch it, emphasising his negative points.
Mention you watched it, powerful drama, really scary as well with the lad being so young... He'll probably watch it on his own and take more from it than if his Mum was having to blackmail him to watch it as she thinks so poorly of him.
