What are the rules on outsiders?

So my question is this: I’ve been seeing my partner/ best friend -we’ve known each other since we were 14 but only began dating a year ago. He’s been in recovery for the past four years but has had a series of relapsed unfortunately. He has a 3 y/o daughter with a young woman he meet very early on in the rooms while attending meetings. I myself do not attend N/A but fully support his recovery. I have taken him to detox and support him placing recovery ahead of everything else. Myself I drink alcohol on occasion socially only. My boyfriend was a hard core drug addict. Fent and other drugs. Myself never touched a drug in my life. Not even w€€D. There are lots of fellowship and NA community events and get togethers that have happened over the course of the past year. I have never been asked or included in any of them. I’d be lying if I’d say by this point that I do feel a little left out. He attends with his daughter and the Mother of his young daughter, I’m not jealous of bio-Mom, but their relationship is very co-dependent which they both realize. Yesterday their was a pool party hosted by his sponsor, his daughter was begging me to come. I ended up seeing the invite it said all clean living people are welcome. Does this mean I wasn’t welcome there?
