I'm hurt that my son told me not to hang out with him and his friends anymore
That sounds terrible. Was there something that you regret doing to your son when he was younger?
I do, I was too strict with him as a child.
You should not make a big deal about it. You should understand that your son needs privacy with his friends and it doesn't mean he hates you.
I really think he hates me...
No, I don't think he hates you at all! It's only natural that teenagers want to start becoming independent and finally becoming their own person. It's really important to respect that, and I'm just saying to give him space and let him come to you now.
