I agree with TB. There are no rules regarding relationships in the first year (or any year of recovery) in NA. The suggestion of staying out of a "romantic relationship" or making any "major decisions" is one that originated in treatment facilities a while back. Although these suggestions aren't from NA doesn't mean that they don't have merit. I recall when I had 3 months or so clean...and although many of the women I saw and met in meetings were attractive to me, I knew that I wasn't in any shape to enter into a relationship...especially a healthy one. Honestly...I was tore up, confused and my feelings were all over the place. That's what I had to offer.
NA teaches us to keep our priorities first. I've seen way too many members (old and new) get distracted by relationships before putting in the work to become healthy themselves, and the results were generally disasterous. Some stay clean, keep coming back and are the wiser from their experience...some don't.
