((Dorton))
Obviously, I'm not a parent and haven't been through this, though I am getting a very good idea on the parenting thing with my 15-year-old niece who lives with me. The things I said I would never do if I had a kid, I've done every one of them at least once.
If your gut says to give him another try at home, after you and your husband have discussed it, write down exactly what the boundaries are and what his consequences are. Tell your son that at this point you have little to no trust in him, and don't know when he will regain your trust and he might as well accept it. If he can't handle living where everyone is watching him like a hawk, find somewhere else to live. This is a consequence and he earned it, just as I did.
If your gut says you've had enough, then that's okay, too. Us A's are very good at finding other places to live, they just usually aren't as comfy as home
Either way, you'll have our support.
Hugs and prayers!
