Please know that as Chy already said, you are welcome to post anywhere you would like to post here, but the Nar-anon forum is really filled with those of us who have gone through similar things to you. You are always welcome there with us, and I know from my own experience - you'll get tons of support and understanding there.
I hope you didn't feel as though you couldn't post there. You love someone who is an addict - that makes you a perfect fit!
Welcoming hugs,
Trisha
