Tryingveryhard,
Sorry I am coming in late, but welcome to SR. I am a mother of an addict 21yo. He did everything your son did to you. I pressed charges against him, which I know is very hard to do. I also made him leave my home. He tried to tell me I should just forget everything he did to me since he couldn't help it. It was the addiction that made him do it. I have yet to hear I'm sorry for stealing from you, or for forging your name to checks. I still love my son, but I hate who he has become because he chose to use drugs.
It is a good idea to try different meetings, I found one for Nar-Anon I really like and it helps me so much. I hope you find the right one for you.
This site has helped me so much over the past year, and it has become a part of my family.
Hugs
