You might be thinking too hard about this. I am new to both groups, and have found every meeting SO helpful. I too have to drive a ways to get to NarAnon, but it is worth every cent, and I am broke at the moment, too.
There are people in both who have BFs or Xs and no one judges them. It is a really safe space, and a place to find community in your struggles. Some parents of Addicts at my last meeting said they still come, even years of sobriety later, so that they can be a source of hope for people new to the journey. If that's not a testament to the power of AlAnon and NarAnon, I don't know what is. No one will judge you. There's lots of love and support. Just go. And remember, you are the key here--your recovery is what matters most.
