Wondering What To Think

My son is 29. He abused drugs as a teenager and escalated to heroin by age 17. I went to alanon, sent him to rehab, counselors etc. I think I got more abused than the drug though. Then, he moved away with his girlfriend, another drug addict, and supposedly got clean. I guess he did, but he is still on suboxone 9 years later. Now, the drug addict girlfriend is out of the picture since 2 years ago and now he is married to a very nice lady who has a 7 year old daughter. Everything was going well, then the wife kicked him out for erratic behavior. He literally became a dictator with anger issues. He'd yell, complain, and NEVER allow anyone to speak. He would sleep until 2pm everyday and get up in an outrage. The wife's parent's, who are well off, are ready for him to be gone too. Now, he called me up all emotional saying he had lost his wife and she was hitting him and lost his daughter. I picked him up and brought him 2 hours to my house since he was in an emotion whirl wind. I took him to the doctor as he had lost 20 pounds in a month and weighed only 110 pounds. The doctor prescribed ativan. Then, I took him back to his home, paid $700.00 to fix his car and left him at a friends house. He has a job there, so he couldn't come back home. My friend, an ex drug addict herself told me he acted like a drug addict and with all his pacing and temper outbursts. She went to pack his things the day he was to come for them and said he had a tubberware lid with scratches all over it and a straw with white powder that made her tongue go numb when she tasted it. He said he crushed his suboxone and that's what the lid was about. Now, he is back with his wife and telling her and my daughter that I dumped him on the street and left him. His wife asked me what kind of mother would do that. I am really in wonderment over the entire incident. I am glad to be home and back to busying myself with other matters. I can't help to think my friend may be right. She told him he needed to stop the lies and get into a program. I think that is a good idea. It's hard to know since he also has hyperactivity disorder as well. Not positive how much I want to know really.
Now he left his wife, went out of state, and now no one knows where he is. Trying still not to worry. It's really hard. My friend said she found a straw cut in two and winded up with powder on the end. It does not look good. I guess I will just pray. Doesn't look like anyone knows anything else to do.
