I'll never get tired of answering, that's why I'm here, so as long as you want to talk about it, I'll be here to listen and respond. :)
He's 16 right? That's so young to be into drugs and alcohol. You're right, he can't do it for you, he can only do it for himself. Sadly, most people have to hit rock bottom before they're willing to do it. He's not there yet.
If you two do break up and he starts using again or drinking, you know that's not your fault. If you don't know it, I'm telling you, it's not your fault! ;)
Substance abuse is often a way to deal with other problems. Sadly it's just heaping more problems onto the existing problems and before you know it, all you have is problems.
He really would benefit from coming here to talk to us.
I've been through a lot of the stuff you're going through, a long, long, long, long (ya, I'm not that young anymore) time ago.
Also, I did a lot of the stuff your boyfriend is doing when I was younger too. It wasn't until I realized that I was digging a hole for myself that I was able to stop. It's not easy, especially when you have other crap going on to boot.
I don't know if I can get him to listen, but I can try.
I've got to run for a bit, time to get my kids to bed, read them a book, you know, mom stuff. I'll be back in around 1 or 2 hours.
I'm so sorry that you feel like you're carrying this burden, it's not fair, and you shouldn't have to go through it. You'll be okay though, really you will. :)
