Hi KrisMarie
Listen to Chino and SpeedyJason, they are correct. I am in a recovery program and I am so thankful for all the friends I have met who are also in recovery.
If anything this will help your boyfriend.
If you love him try to be supportive and maybe look into going to a support group of your own as Chino said.
I know it must be hard as you might feel threatened by his new life/friends but wouldn't you rather him have friends that understand him instead of him feeling alone and possibly relapsying.
I plan on going to my first meeting next Thursday but maybe you should go with him? I'm not sure if that's allowed but if you go it might open your eyes and you will see his new friends in a different light.
Most recovering addicts are the nicest people out there because they are non judgemental. Give his new friends a chance, who knows! you might end up really liking them.
Take Care!
