My 23 year old son is in the Pacific Northwest. He impulsively left the Midwest about a month ago, and as I've learned from his ex girlfriend , he is using heroin and serially hooking up with women and then robbing them. There are several Facebook posts I've seen from women in states he's passed through talking about how he's stolen money, laptop, id's and credit cards. He is self diagnosed Borderline (BPD)( which I agree with). He stays in contact with me via text but will not admit to anything. He has a car and is living in it. I'm terrified at the prospects for his future. I'm beginning to lose hope for him, since he will not be honest with me at all. I feel great sympathy for all of you and all I can do is go day by day. This is horrifying.
