Yes and no.
We do have a sub-group for significant others. They also have their own (private) chat group on Yahoo!
SOs are welcome at the meeting, and even encouraged. The SO Group leader is at virtually every meeting. If necessary, the SOs can go to another room to have their own meeting. This group will be glad to help your wife/partner feel less threatened by your "hobby."
They do not offer "counseling" other than peer-to-peer discussion.
If you can't get your SO to a meeting, they may want to at least email the SO group leader through this web site.
